QDups
-----


QDups is designed to help hard disk users locate and remove duplicate
files from their hard disks. Before QDups, getting rid of duplicate
files meant searching through a hard disk, then manually deleting the
unwanted files. This program handles the job automatically. QDups can
free up large amounts of space on your hard disks, giving you maximum
disk space. You'll be amazed at the extra room.

Using QDups, you can:

1. Look for duplicate files on one or more disk drives.
2. Check to see whether your hard disk already contains files on a
floppy disk.
3. Delete individual duplicate files with a keystroke.
4. Create a file containing a list of duplicate files for review.
5. Print a list of duplicate files for review.
6. Compare duplicate files for differences.


System Requirements
-------------------

QDups will run on any IBM-compatible computer. It needs DOS 2.1 or
higher and can use monochrome or color monitors. Memory requirements
for the program vary according to the number of files on your disks.
If you have 640K, you'll be able to handle 40 megabyte
disks easily.


Installation
------------

To install QDups, copy the file, QD.EXE, into a directory on your hard
disk. For easiest use, copy the program into a directory named in the
PATH statement in your AUTOEXEC.BAT file. That way you can use the
program from any directory. If you need more information about the
PATH command, see your DOS manual.

Running QDups
-------------

If you give the command, QD , by itself, you'll see a screen
displaying the proper command syntax for the program. You need to add
the drive letters you want to check.

If you want to search for duplicate files on drive C:, the command would
be:

QD C .

To check drives C: and D:, the command looks like this:

QD C D

To check drives A:, C:, D:, and E:, use this format:

QD A C D E

Once you give the correct command, you'll see a screen displaying the
files one at a time, as they are checked. Duplicate files appear in a
window to the right as they occur. The window on the far left displays
statistics as the program proceeds, including the number of duplicate
files and information on disk space. You can stop the process by
pressing any key.

Once all the disks are checked, the screen changes. Now the left
window displays totals for disk space, the number of duplicate files,
and other information. In the right window, the duplicate files are
found with size, date, time and attribute information for each file.
Use the cursor keys to move the highlight bar over each file. When you
reach the bottom of the screen, the display scrolls automatically.

Press - to see the available commands. Here's a list of the
commands:

Writes the entry under the highlight to the file QDUPS.LOG.

Writes the entire list of duplicates to the file QDUPS.LOG.

Compares two files. You'll be prompted to mark two files. Press
to mark the highlighted file. Differences will be
displayed at the top of the screen.

- Prints the highlighted entry on your printer.

- Prints the entire list of duplicate files.

- Deletes the highlighted file from the disk. You'll see a
line through the file information showing you that it has been
deleted.

Displays statistics on a drive, if you've selected
multiple drives.

As you move the highlight bar, the top left corner of your screen
displays the drive and directory information about that file. That
helps you decide which of the duplicate files to delete. Be careful
not to delete files which have the same name, but are actually
different. For example, you may have several different files with the
filename, README.DOC, since that's a common name. Check file size, date
and other information before deleting.

To quit the program, just press .


Advanced Techniques
-------------------

QDups can use your DOS environment to set two characteristics. You can
tell the program where to send the QDUPS.LOG file and to use special
monochrome attributes if you have a composite monitor connected to your
CGA card.

You can install QDups by giving the following SET commands before
running the program. If you like, you can include them in a batch file
used to start the program.

SET QD=[path] Creates a path for storing QDUPS.LOG files.
Substitute your own path information.

SET QD=;C Suppresses color for those using composite video.

SET QD=[path];C Combines both options.

If you ignore these environment settings, the QDUPS.LOG file will be
written to the current directory of the disk being checked. If you need
more information about the SET command, see your DOS manual.
