                              DISKDUPE TRIAL MANUAL




                                   INTRODUCTION



     DISKDUPE DUPLICATES DISKS FAST!

     Thank you for trying DiskDupe. DiskDupe is the  best program to automate
     your disk duplicating needs. DiskDupe can duplicate disks amazingly fast
     and without any fuss. Other programs simply don't measure up to DiskDupe
     in terms  of  speed, bad  disk  detection, ease  of  use,  and depth  of
     features.

     DiskDupe duplicates, formats  and compares  disks up  to 6  times faster
     than DOS. It copies even high-density disks in a  single drive - without
     swapping! DiskDupe senses  when you  put a  disk in  the drive  and goes
     right to work.  If a disk  needs to be  formatted, that's taken  care of
     automatically. To perform  at maximum speed,  DiskDupe bypasses  DOS and
     the BIOS and talks directly to your floppy controller.


     REQUIREMENTS

     - IBM PC, PS/2 or Compatible
     - DOS 2.0 or later
     - 300k RAM
     - Hard Disk (or two floppy drives and 100k Expanded Memory)




                                   INSTALLATION


     HARD DISK INSTALLATION

     To install DiskDupe on your hard disk:

     1.    Type: MD C:\DISKDUPE  <Enter> to make a  subdirectory for DiskDupe
     on your hard disk.

     2.   Type: CD C:\DISKDUPE <Enter> to change to that directory.

     3.   Insert the DiskDupe  program disk in  drive A:, or  the appropriate
     floppy drive, and type:  COPY A:\*.* <Enter> to  copy the files  to your
     hard disk.

     4.   Type DISKDUPE <Enter> to run DiskDupe.

     DiskDupe  searches  the  current   directory  and  your  path   for  its
     configuration file DISKDUPE.DAT. You can add  the \DISKDUPE subdirectory


                                      Page 4


                              DISKDUPE TRIAL MANUAL



     to the path statement in your AUTOEXEC.BAT file so that  you do not need
     to change to the \DISKDUPE subdirectory every time you run DiskDupe.


     NETWORK INSTALLATION

     Running DiskDupe on a network allows  you to take full  advantage of the
     multiuser environment and allows  you to share  image files. As  long as
     only one computer is using DiskDupe at a time,  you can install DiskDupe
     on the network under the terms  of this license agreement.  If more than
     one person  will be  using DiskDupe  at the  same time,  contact us  for
     information on a site license.

     If you are the only one using DiskDupe on your  network, you can install
     it as described  above in  the hard disk  installation. However,  if you
     would like  multiple workstations  to be  able to  access DiskDupe,  the
     network administrator  should  install  it  according to  the  following
     instructions.

     1.   Copy  all  the  files   from  the  DiskDupe  disk   into  a  shared
     subdirectory on the network.

     2.   Copy the file DISKDUPE.DAT from the shared  subdirectory to a local
     subdirectory that DiskDupe will be started from.

     3.   DiskDupe searches  the  current  directory  and  the path  for  its
     configuration  file  DISKDUPE.DAT,  which  is  updated  with  DiskDupe's
     current settings  each  time  you  exit.  If DiskDupe  cannot  locate  a
     DISKDUPE.DAT file, it  creates one  in the directory  from which  it was
     started. There are several ways for a user's configuration to be saved:

        - Add the local subdirectory to the user's PATH statement.

        - Keep "Use CMOS for A&B" set as "Yes" in the shared subdirectory. If
        started with the shared DISKDUPE.DAT, DiskDupe will start up with the
        A: and B: drives tailored to the specific workstation's configuration
        at the time it was turned on or rebooted (drive settings can still be
        changed from within DiskDupe  at any time). This  alleviates the need
        for some users to have a local DISKDUPE.DAT file.

        - Start DiskDupe from the  local subdirectory or create  a batch file
        to do so.


     FLOPPY DRIVE INSTALLATION

     If  the  computer doesn't  have a  hard disk  and is  not attached  to a
     network, you can run DiskDupe on  a dual floppy disk system  if you have
     at least  100k of  expanded memory.  It  is best  if you  can leave  the
     DiskDupe disk in one drive and use the other drive for copying.



                                      Page 5


                              DISKDUPE TRIAL MANUAL



     If you need to use both drives for copying, start DiskDupe and set it up
     exactly the  way you  want it.  Next  exit DiskDupe  to  save the  setup
     information. Then start DiskDupe again and choose an option under the Go
     menu. You can  now take out  the DiskDupe disk  and use both  drives for
     copying.


     SOFTWARE COMPATIBILITY

     - Windows 3.1: If you receive an error message saying  the DMA buffer is
     too small, add the  line DMABufferSize =  018 to the  Windows SYSTEM.INI
     file in the [386Enh] section.

     - QEMM and SmartDrive  3.1: If you receive  an error message  saying the
     DMA buffer is  too small,  change your  CONFIG.SYS to  "QEMM386.SYS DB=3
     DMA=15" to load  QEMM. You don't  need the DB=3  parameter if  you don't
     have a SCSI hard disk.

     -  OS/2:  For  maximum  speed,  open  the  DOS   settings  box  for  the
     DISKDUPE.EXE  object.   You'll  need   to  set   HW_TIMER  to   Off  and
     IDLE_SENSITIVITY to 100 for the DOS session.



                               NAVIGATING THE MENUS

     DiskDupe supports  both mouse  and keyboard  use. When  you first  start
     DiskDupe, you'll see a menu bar across the top of the screen, from which
     you can select pull-down menus,  either by clicking on  each option with
     the mouse or moving the highlight bar with the  cursor keys and pressing
     <Enter>. Once the  menus are displayed,  click on a  menu item  with the
     mouse to select it, or use  the Up/Down arrow keys  to scroll vertically
     through each menu  and the Left/Right  arrow keys to  move from  menu to
     menu. Once you  have made the  desired changes in  a box, the  <Esc> key
     will get you out of any menu.

     Although the mouse and keyboard functions are generally interchangeable,
     you may have to use <Enter>  or <Esc> to select or  cancel some settings
     that are specified in menu boxes.

     Note: When  using  the  keyboard,  you  must press  <Enter>  to  make  a
     selection. If you scroll down a menu, and then move  to a different menu
     without making a selection, the highlight bar will remain on the setting
     you scrolled down to, but the highlighted setting will not be selected.


     BASIC OPERATION

     DiskDupe has  three  basic  operations  - duplicating,  formatting,  and
     comparing - each of which is selected from the Go menu.



                                      Page 6


                              DISKDUPE TRIAL MANUAL



     Duplicate makes a copy  of a disk, Format  prepares a new disk  for use,
     and Compare  checks that  two or  more disks  are identical.  The Copies
     setting controls the number of copies that are made.  Enter 0 for copies
     to copy continuously. (NOTE: The Trial edition only allows 5 copies, and
     Lite Edition allows 10. All other versions have no limit)

     Whether you are Duplicating,  Formatting, or Comparing,  DiskDupe always
     works from the Source drive to the Destination drive. It copies from the
     source disk, sometimes called  the master disk,   to the destination, or
     target disk.  Sometimes, for instance  when you format a  disk, only the
     Destination setting is used.

     Although the simplest way  to use DiskDupe is  to copy from one  disk to
     another disk, other modes are useful for certain tasks. Two other common
     ways of working with disks in DiskDupe are Relay  and Cascade. There are
     also variations, such as creating an  image of a disk on  your hard disk
     and making copies from that file. For each variation, there are settings
     that control how each of the basic operations  work. The basic technique
     goes like this:

     1.   Try working from right  to left when changing  menu settings. Start
     with the  Options  menu, and  then  check the  menu  settings for  Disk,
     Destination, and Source. For the Disk setting, you can usually use Auto.
     DiskDupe then automatically sets the type of disk.

     2.   From the Go menu, decide how many Copies you want  or the number of
     times you want something done.  In some cases, this  setting is ignored.
     (NOTE: The Trial edition only  allows 5 copies, and  Lite Edition allows
     10. All other versions have no limit)

     3.   Select the operation, usually Duplicate, Format, or Compare.



                                  COPYING DISKS

     Whether you're  duplicating, formatting,  or comparing,  many variations
     are possible  in  DiskDupe. Copying  from  one disk  to  another is  the
     simplest way to  make new  disks. Variations of  this include  Relay and
     Cascade introduced in detail in this chapter.

     Regardless of  the options  chosen, DiskDupe  makes an  exact copy  of a
     disk, including  hidden  and system  files,  subdirectories, and  volume
     labels. However,  DiskDupe  cannot  make  duplicates of  copy  protected
     disks.


     DISK TO DISK

     The most straightforward way  to duplicate is to  copy from one  disk to
     another. This is useful for making a specific number  of copies of disks


                                      Page 7


                              DISKDUPE TRIAL MANUAL



     of different types  and sizes. For  example, if you  want 5 copies  of a
     disk, you would select Duplicate with Copies set to 5.

     You do not explicitly need to set up DiskDupe to copy "disk to disk". It
     is the standard way it works.  Below are step-by-step instructions.

     1.   Move to  the Type  menu. Use  the  <Up> and  <Down>  arrow keys  to
     highlight the type of disk you  want to copy, or select  Auto, and press
     <Enter>.

     2.   From the Destination menu,  select the drive  to which you  want to
     copy.

     3.   Under Source,  indicate the  drive  from which  you  want to  copy.
     Source and Destination can be the same drive, but do not need to be.

     4.   Move to the Go menu and  set the number of copies that  you want to
     make. If you want DiskDupe  to copy continuously until  you press <Esc>,
     enter 0 for the number of copies. (NOTE: The Trial edition only allows 5
     copies, and Lite Edition allows 10. All other versions have no limit)

     5.   Highlight Duplicate and press <Enter>.

     DiskDupe will prompt you to put the master disk in  the Source drive and
     the drive  light will  turn on.  As soon  as you  close the  drive door,
     DiskDupe will start  reading the disk  into your computer's  RAM memory,
     using your  hard  disk  as  virtual  memory if  necessary.  This  allows
     DiskDupe to make as many copies as you want without having to reread the
     master disk.

     Notes:

     - Although you can duplicate 360k  disks in a 5.25", 1.2Mb  drive, it is
     not recommended, particularly if  the disks might need  to be read  in a
     360k drive. A 1.2Mb drive writes a narrower track than  a 360k drive, so
     it does not make a very good 360k duplicate.

     - DiskDupe will  not successfully  copy disks  that are  copy protected.
     However, it will allow you to make copy protected disks of your own.

     - Although DiskDupe is DOS-based,  it will allow you  to duplicate disks
     of other  formats, including  Mac high-density,  Xenix,  Unix, and  Midi
     disks. DiskDupe can copy  Unix disks that have  an interleave of  3, but
     the copies it makes will have an interleave of 1.


     IMAGES

     If you frequently make copies of  one disk, making an image  of the disk
     on your hard drive saves time  and avoids unnecessary wear  on the disk.
     The only drawback is the hard disk space that images take up.


                                      Page 8


                              DISKDUPE TRIAL MANUAL



     To create an image, set Source to the drive with the  master disk in it.
     Set Destination to File  and then type in  a file name.  DiskDupe images
     usually use the extension .DDI. Then select Go,  Duplicate to create the
     image.

     To use the image, set Source to file, and press <Enter> when you see the
     *.DDI. DiskDupe  will then  show you  all the  images you  have created.
     Select the one you want and  press <Enter>. Then set  Destination to the
     drive you want to copy to and select Go, Duplicate to make the copies.


     RELAY

     Relay is an extremely  efficient method of  backing up program  disks or
     making copies of  a shareware library.  To use it,  first make  sure all
     your master  disks have  write-protect tabs  on them.  Relay senses  the
     write-protect tabs and automatically  reads and copies the  master disks
     to all the non write-protected disks after each master disk. This allows
     you to make copies of different  master disks of one  type without using
     the keyboard.

     Then set Source to  Relay, Destination to  A: and select  Duplicate from
     the Go menu.  Put in  the first master  disk and  let DiskDupe  read it.
     Afterwards, put in as many disks  as you want to copy. When  you want to
     start copying from the next write-protected master,  just insert it into
     the drive. DiskDupe will  sense the write-protect  tab and read  the new
     master disk without a keystroke.

     1.   To use Relay,  make sure all  your master disks  have write-protect
     tabs on them.

     2.   For Destination, select the  drive to which  you want to  copy. For
     Source select Relay.

     3.   Under Go,  select Duplicate.  The number  of copies  doesn't matter
     when using Relay.

     4.   Put in the first write-protected master disk  and let DiskDupe read
     it.

     5.   Insert the disks you want the master copied to.

     6.   When you are ready  to start using the  next write-protected master
     disk just put it in.  DiskDupe will recognize the  write-protect tab and
     start reading this in as the next master disk.

     7.   When you are finished, press <Esc>.

     Caution: If your master  disks do not  have write-protect tabs  on them,
     they will be overwritten.

                              DISKDUPE TRIAL MANUAL



     CASCADE

     If you have more than one  floppy drive of the same type  and are making
     multiple copies, you can use Cascade to get more  efficiency out of your
     drives. Using Cascade is  similar to copying from  A: to B: - reading a
     disk from one drive and making a copy in another - except that, once the
     first disk is  read, DiskDupe  cycles through and  makes copies  in each
     drive.

     1.   Choose Cascade from the Destination menu.

     2.   Choose the Source drive or Image.

     3.   Put a write-protected master disk into the first drive.

     4.   Select Duplicate from the Go menu.

     DiskDupe will read the  first disk and then  wait for you to  remove the
     disk and insert new ones in all the drives. DiskDupe will sense the disk
     change, make a  copy in  the first drive,  and then  switch to  the next
     drive to make a  copy. It will make  copies until it reaches  the end of
     the cycle, where the Cascade Pause  feature waits for you  to change the
     disks in all the drives. DiskDupe will sense when you  insert a new disk
     in the first drive and resume copying immediately.

     DiskDupe will continue  copying until the  desired number of  copies has
     been made or until you  hit <Esc> to break  the cycle. If a  bad disk is
     encountered, you will have  to remove it and  insert a new disk  in that
     same drive before DiskDupe resumes duplicating.

     Note:  The  IBM   PC  and   compatibles  cannot   copy  to   two  drives
     simultaneously.


     RELAY AND CASCADE

     You can also  combine Cascade  with Relay.  In such  a setup,  the first
     write-protected master disk is  read from the  first drive in  the cycle
     and will be copied  to every non  write-protected disk inserted  in that
     drive. In the  second drive another  master disk is  read and  copied to
     each non write-protected disk inserted in that drive.



                                 FORMATTING DISKS

     With DiskDupe, you can either format a disk as it is being duplicated or
     separately, by choosing  Format from  the Go menu.  When you  copy disks
     with Duplicate, DiskDupe will  detect whether a disk  has been formatted
     and, if necessary, format it while copying. Format is a separate feature



                                     Page 10


                              DISKDUPE TRIAL MANUAL



     used whenever  you want  to just  format some  disks or  preformat disks
     ahead of time for later use with DiskDupe. To format disks:

     1.   Go to the Options  menu to select  the Format and  Verify settings.
     The options are discussed below.

     2.   If you are  formatting a 720k  disk in a  1.4Mb drive, set  Disk to
     720k otherwise leave it set to Auto.

     3.   Set Destination to the drive you will use to  format the disk. This
     can be Cascade to use both drive. Source is not used when formatting.

     4.   Select Format from the Go menu.


     QUICK ERASE

     To do  a quick  erase, set  Format  under the  Options menu  to Only  If
     Necessary and set Verify to Only After Format.

     Reformatting a disk that has been previously  formatted takes only about
     2 seconds per  disk. This effectively  wipes out the  data on a  disk by
     writing over the disk's FAT (File Allocation Table) and directory table.
     DiskDupe will  write the  first couple  of  tracks, where  the file  and
     directory information is located, realize that the  disk doesn't need to
     be formatted,  and prompt  you for  another disk.  If you  run a  DIR or
     CHKDSK on the disk, you will see that the disk is indeed empty.

     If you also want to recheck  the disk to make sure there  are no damaged
     areas, set the  Verify option  to Always.  This is  quicker than  a full
     reformat, but will check the entire disk for defects.

     Note: Although  the  disk  appears blank,  some  of  the data  is  still
     physically on the disk.  The only time this  might pose a problem  is if
     the disk contains sensitive information that you want to be sure to wipe
     off completely. If so, use the full reformat option.


     FULL REFORMAT

     To do a full reformat, set Format under the Options menu to Always.

     Use full reformat if  you plan to use  an old disk  as a master  disk or
     want to completely erase all the data on it.


     FORMAT COMPATIBILITY

     When DiskDupe formats disks using Format  under Go, it places  a DOS 3.3
     boot track on the disk. This is compatible with all  versions of DOS. If
     you want to format a disk with the boot track of another version of DOS,


                                     Page 11


                              DISKDUPE TRIAL MANUAL



     or make a bootable disk or make formatted Unix, Midi or Mac high density
     disks, follow these instructions.

     1.   Format a disk using the normal format command for that system. With
     DOS this is FORMAT or FORMAT /S.

     2.   Use DiskDupe to make a copy of this disk. If you  want you can also
     create an image file of this disk and use that as the Source.

     If you  are  using a  master  disk formatted  with  DOS  4.0 or  higher,
     DiskDupe will copy the serial number of the master disk without changing
     it.



                                     CLEANING

     To ensure good copies  and avoid strange  problems, it is  critical that
     the drive heads be  kept clean. Dirty heads  can cause good disks  to be
     rejected and bad disks to be passed.


     HOW DRIVES GET DIRTY

     Drive heads get dirty  in two ways. Particles  on the disk  surface like
     dust and  cigarette smoke  can stick  to  the head  and/or the  magnetic
     coating on the disk rubs off on the head. These coatings vary in quality
     and they all absorb moisture. Poor quality disks that have been in humid
     environments can clog the drive heads after just 50 or 60 disks.

     When the head gets dirty, it no longer makes good  contact with the disk
     and the dirt  particles diffuse  the reading  and writing  process. This
     produces  erratic  results.  Some  disks  work  fine  while  others  are
     inexplicably rejected.


     HOW OFTEN TO CLEAN

     We recommend that you clean the drive heads every 500 disks, or at least
     once a month. Sometimes in humid or dirty environments, you will need to
     clean the heads  every 100  disks. If  you start  experiencing a  lot of
     rejected disks or have other problems, it is always a good idea to clean
     the heads.

     When drives are extremely  dirty, you can actually  see the dirt  on the
     head. After you remove the cover, you will be  able to see reddish-brown
     spots on the white ceramic piece attached to the moveable head-frame.

                              DISKDUPE TRIAL MANUAL



     CLEANING THE DRIVE

     To clean  the  drive,  use a  good  wet-dry  type cleaning  disk.  Under
     DiskDupe's Destination menu,  select the drive  you want to  clean. Then
     choose Clean from the Go menu. Insert the cleaning disk in the drive and
     press <Enter>. The drive will be cleaned for 15 seconds.

     While cleaning, DiskDupe moves the head back and  forth across the disk.
     This provides the  best possible  cleaning and  makes sure  the cleaning
     disk is evenly used. Be sure to discard the cleaning disk if you see any
     discoloration on it or it has  been used past the  recommended number of
     cleanings.

     If you clean your drives regularly, a 15  second cleaning is sufficient.
     However, if your drives  are especially dirty, several  cleanings may be
     required. In extreme cases, it is  necessary to clean the  drive head by
     hand with a Q-tip and isopropyl alcohol.

     Cleaning the drive  does not wear  it out. A  dirty drive  will actually
     wear out faster because of the abrasive action of the dirt.



                                 DISK CONVERSION

     DiskDupe allows  you  to convert  certain  types of  disks  to disks  of
     another physical size, such as a 5.25", 1.2Mb disk to a 3.5", 1.4Mb. You
     can, for example, copy a program's 5.25" program disks to 3.5" disks for
     installation on a laptop which only has a 3.5" drive.

     Converting disks is just a special application of the Duplicate command.
     The table below indicates which disks, drives, and settings to use for a
     conversion.  The  conversions  listed   are  the  only   ones  presently
     supported.

     Conversion          Disk type      Drive Type
     -------------       ----------     -------------------
     360k to 3.5"        720k disk      720k or 1.4Mb drive
     720k to 5.25"       360k disk      1.2Mb drive
     1.2Mb to 3.5"       1.4Mb disk     1.4Mb drive

     For the 3.5", 720k to 5.25" conversion, copy to  a low-density 360k disk
     in the 1.2Mb drive.  If you get an  error on several disks,  try using a
     1.2Mb disk  instead. This  disk will  be formatted  to 720k  capacity by
     using the area between  the tracks. If  a computer has  problems reading
     the files on the disk, even  though it recognizes the disk and  can do a
     DIR of it, use the  FIX720.COM program. This is  a small memory-resident
     program that  allows such  computers  to read  this  5.25" disk.  (NOTE:
     FIX720 is included with the registered versions of DiskDupe.)




                                     Page 13


                              DISKDUPE TRIAL MANUAL



     DiskDupe transfers  the  information  track-by-track,  including  volume
     labels, subdirectories, hidden  and system  files. During  a conversion,
     the destination  disk will  be formatted  to  the same  capacity as  the
     source disk. So if  you are copying from  a 5.25", 360k disk  to a 3.5",
     720k disk, the 3.5" disk will have a capacity of 360k.

     Track-by-track conversion won't  copy from  a higher  density disk  to a
     lower density disk, even if the higher density disk has just a few files
     on it. In this case, it's better to use the DOS Copy command to transfer
     the files.

     Note: If you are copying disks to send to others,  we recommend making a
     master for each  disk size,  rather than  using track  conversions. This
     allows you to use the full  capacity of the disk and  will alleviate any
     possible problems that other computers might have reading these disks.



                                     OPTIONS


     CASCADE PAUSE

     If you intend to change each  disk as it is copied, you  can set Cascade
     Pause to Off  under the Options  menu. DiskDupe will  cycle continuously
     and overwrite the disks in the  drives, including the master  disk if it
     is not write-protected. If you prefer  to change the disks  all at once,
     leave Cascade Pause set to On, and DiskDupe will wait for you to do so.

     Example

     Using Cascade with drives A: and B:: While the master disk is being read
     from drive A:, you put a blank disk in drive B:. As  soon as DiskDupe is
     finished reading from  drive A:, it  will start writing  to the  disk in
     drive B:. If Cascade Pause is  set to On, DiskDupe will wait  for you to
     hit a key at  the end of each  cycle, indicating that you  have replaced
     all the  disks. With  Cascade Pause  set to  Off, you  must remove,  and
     replace, the disks as they are copied or DiskDupe will overwrite them.


     DISK MENU

     Normally you can leave  this set at  AUTO to let  DiskDupe automatically
     sense the type of disk you are using. When you  are formatting and doing
     diagnostics on a  1.4Mb drive, DiskDupe  will assume you  want to  use a
     1.4Mb disk. If you want to  use a 720k disk, you will  need to select it
     manually. The same is true for a 360k disk in a 1.2Mb drive. Also if you
     are copying non-DOS disks like Unix, Midi or Mac  high density, you will
     also need to select the copy type manually.




                                     Page 14


                              DISKDUPE TRIAL MANUAL



     NOTE: Although you can duplicate 360k disks in a  5.25", 1.2Mb drive, it
     is not recommended. The 5.25",  1.2Mb drives write a  smaller track than
     usual so they do not make very good 360k duplicates.


     FORMAT OPTION

     The Format  and  Verify options  are  used to  help  speed  up the  disk
     duplicating time. If you always use new disks when  making copies, go to
     FORMAT under the  OPTIONS menu, press  <ENTER> and  then select  ALWAYS.
     This will save a  few seconds that  DiskDupe normally takes  to identify
     that a disk is blank and  shift into Format mode. When Format  is set to
     ALWAYS, a 360k disk will take less than 58 seconds to duplicate.

     If, however, you  sometimes use  disks that  are pre-formatted,  you can
     save a lot of  time by setting FORMAT  to  ONLY IF NECESSARY . This will
     skip the format step on disks that have been  pre-formatted. You can use
     this option even if you use a combination of pre-formatted and new disks
     because DiskDupe will still sense  when a disk is  new and automatically
     shift into format mode for that disk.


     VERIFY OPTION

     If you are confident that the disks you have pre-formatted have not been
     subsequently damaged, you can also  set VERIFY to ONLY AFTER  FORMAT. On
     pre-formatted disks this  can cut  the duplicating time  on a  360k disk
     down to less than 16 seconds per disk.

     Be aware, however, that if the  disks have been damaged  after they were
     formatted (for  instance,  someone accidently  touched  the floppy  disk
     surface), DiskDupe will probably not detect this damage if VERIFY is set
     to ONLY AFTER  FORMAT. Duplicating  times for  pre-formatted disks  when
     Verify is set to ALWAYS are still fairly quick.


     COMPARE OPTION

     To compare a disk byte-by-byte to the master during  verify, turn On the
     Compare option under Options menu.

     Compare provides a more thorough check  than a Verify. You  can run both
     together if you are running DiskDupe  on a 386 or  later model computer.
     Using both Verify  and Compare  will not slow  down the  duplication any
     more than running just one. Under Options, select On for Compare and set
     Verify to Always.

     On some 286's and slower computers, compare during verify might slowdown
     the copying speed. If  your computer passed the  diagnostics tests under
     the Go menu, you can turn Compare Off and still catch 99.97% of all disk
     errors.

                              DISKDUPE TRIAL MANUAL



     TEMP FILE

     The Temp File is  the file on your  hard disk where DiskDupe  stores any
     part of the disk image that will not fit in memory. If you have at least
     640k of RAM memory in your computer and are  duplicating 360k disks, the
     entire disk will  fit in  memory and will  not have  to be  buffered. If
     however, you are duplicating another type of disk or  don't have as much
     memory, part of the disk will be buffered to this file.

     DiskDupe will only  store the  parts of the  disk with  data on  it. For
     instance, if you  are duplicating a  disk that is  only half  full, only
     that half of the disk that has data on it will be stored.

     Note: If files have been erased from a disk, DiskDupe may be fooled into
     thinking that there is  more data on the  disk than there really  is. To
     help DiskDupe work most efficiently, it is best to use a newly formatted
     disk as your master disk.



                                  OTHER FEATURES


     AUTOMATIC DISK SENSING

     DiskDupe automatically senses  when you change  disks without  having to
     touch the  keyboard.  This  will  speed  up your  duplication  and  also
     eliminate errors.

     To sense a  disk change, DiskDupe  needs to keep  the drive on.  So when
     DiskDupe alerts you, it is okay to change the disk even though the drive
     light is still on.


     BAD DISK ALARM

     DiskDupe sounds an alarm when it  encounters a bad disk and  asks you to
     press the <ENTER> key. This alerts you that there is a bad  disk to make
     sure you don't accidentally put it in the good disk pile.



                                  MAXIMUM SPEED

     There are several  ways you can  optimize the speed  of the  copies made
     with DiskDupe.

                              DISKDUPE TRIAL MANUAL



     CLEAN MASTER

     DiskDupe works faster when the  master disk is "clean".  This means that
     the master disk was formatted before any files were copied to it.

     Using a clean disk, DiskDupe is able to sense which part of the disk has
     valid data on it and only duplicate that part of the disk. If you have a
     master disk which  has had many  different files copied  to it  and then
     erased, DiskDupe will have to duplicate the entire  disk even though all
     of the disk might not contain real data.

     To make a clean master disk, first format a disk. Then  use the DOS COPY
     command to copy the necessary files onto this newly formatted disk. This
     disk can now be used as your clean master disk.


     FORMAT AND VERIFY OPTIMIZATION

     1. Pre-format  the disks.  This can  be  done by  copying  from a  blank
     formatted disk. The  disks will  be formatted and  verified and  any bad
     disks will  be  rejected. You  can  format disks  at  any  time that  is
     convenient.

     2. Use these pre-formatted disks  later when you make  copies. Make sure
     that FORMAT is set to ONLY IF NECESSARY and VERIFY is set to  ONLY AFTER
     FORMAT on the SETUP menu.

     3. If you are  nervous about not verifying  the disk after you  write to
     it, set the VERIFY option to ALWAYS. This will increase the duplicating
     times but will re-verify the entire disk.


     DUPLICATING TIMES

     The following table shows how long it takes DiskDupe to duplicate disks.
     If the source disk is not completely full, the duplicating times will be
     faster than this.

     Disks copied in one hour using DiskDupe. All these  times assume that it
     takes two seconds to change the disk.


                              360K      1.2Mb     720K      1.4MB
                              -----     ------    -----     -----
     Blank Disks              62        38        32        32
     Pre-formatted/verify     106       65        45        45
     Pre-formatted            200       126       75        75

                              DISKDUPE TRIAL MANUAL



     Notice how much time you  can save if you  pre-formatted disks yourself.
     However, if you buy disks that  have already been formatted  for you, we
     recommend that you  set Verify  to Always. This  insures that  any disks
     that are bad will be detected.

                                   BATCH FILES

     All DiskDupe parameters can be  entered from the DOS  command line. This
     allows you to create DOS batch files to automate the use of DiskDupe.


     COMMAND LINE

     You can enter all the information on the DOS command line that you would
     normally have to enter by using the DiskDupe menus. Here is an example:

               DISKDUPE  A:  B:  /C5  /DUP

     This will  start DiskDupe  with A:  as the  source drive  and B:  as the
     destination drive and will  make 5 copies. The  /DUP statement instructs
     DiskDupe to start duplicating and then return to DOS without stopping at
     the menus. This is useful if you want to use DiskDupe in a batch file.

     The A: is the Source and can be a drive, a filename or the word RELAY.

     The B: is the  Destination and  can be  a drive  or a  filename. To  use
     Cascade drives, use AB: like  DISKDUPE D1 AB:

     The /C5 sets the number of copies to 5.

     The /C is called  a switch. There  are many different  switches you  can
     use. You  can use  as many  or as  few switches  as you  want. The  next
     section lists all the switches.


     COMMAND LINE SWITCHES

            /DUP   Starts duplicating without pausing at the menus and
                   returns to DOS when finished.

            /FOR   Starts formatting without pausing at the menus and returns
                   to DOS when finished.

            /CLEAN Starts cleaning without pausing at the menus and returns
                   to DOS when finished.

            /TEST  Starts the diagnostics without pausing at the menus and
                   returns to DOS when finished.

            /DAT   Use alternate .DAT file for different duplicating jobs.
                   Example /DATJOB1.DAT

                   Example: /T720  Specifies a 720k copy.

            /S     Sets the type of installed drive.
                   For drive, use one of the following:
                    A:, B:
                   For setup information, use one of the following:
                    360, 12, 720, 14
                   Example: /SA:12  Specifies the A: drive is a 1.2M High
                   Density drive

            /CMOS  "YES" uses CMOS bootup configuration for A: and B: drives,
                   "NO" does not. Example: /CMOSYES

            /TF    Allows the user to set the option for the temporary file.
                   Example: /TFDISKDUPE.TMP  Sets the temporary file to
                   DISKDUPE.TMP


     BATCH FILE EXAMPLE

     You can  combine DiskDupe  commands  into DOS  batch  files to  automate
     sequences of tasks.

     The following is a batch file that reads in a source  disk and creates a
     disk image file and makes 10 duplicates.

               DISKDUPE B: DISK1 /DUP
               IF ERRORLEVEL 1 GOTO END
               DISKDUPE DISK1 B: /C10 /DUP
               :END

     Notice that you  can test if  there was a  problem using  the ERRORLEVEL
     command. An ERRORLEVEL  of one  or greater indicates  that there  was an
     error.



                                 TROUBLE SHOOTING


     COMMON PROBLEMS

     PROBLEM: After I copy a disk using DiskDupe and then try to  do a DIR on
     it, I get an error reading the disk.
     ANSWER: Take the disk out of the drive. Type  <CTRL-C> several times and
     put the disk back in.

     PROBLEM: On my PS/2 DiskDupe reports an Internal Error 2187.
     ANSWER: From the DOS prompt type:

     DEL DISKDUPE.DAT
     DISKDUPE /CMOSNO /SA:14

     QUESTION: On my  PS/2 it  copies the first  disk fine  but then  makes a
     grinding noise and sometimes I get a "Bad Seek Error".
     ANSWER: Some  of the  PS/2 drives  can't  step at  the  proper rate.  To
     compensate for this, under Setup tell DiskDupe that it  is a 720k drive.
     You will still be able to  copy both 720k and 1.4Mb disks  but you won't
