INTRODUCTION

Find Duplicates is an utility program for IBM PCs equipped
with hard disk drives. Find Duplicates will search a
specified drive and locate all duplicate files.

Once the duplicate files are located they are displayed on
the screen. Files can be tagged for deletion, viewed, printed
or deleted.

Find Duplicates was written in Turbo Pascal 5.0, utilizing
Turbo 5.0 Professional by Turbo Power Software.

The program requires 256K of RAM and a hard disk.


GETTING STARTED

To run Find Duplicates, simply type FD at the Dos prompt
which can be followed by two optional command line param-
eters. The syntax is:

FD /d= /bw

The first parameter, /d=, is entered when the drive to
be searched IS NOT the currently logged drive. The second pa-
rameter forces the output to be in black and white. This is
useful for laptop computers which have LCD screens.

The following are valid examples on starting Find Duplicates.

EXAMPLE:
You are logged onto drive C and want to find
all the duplicate files on drive C.
C:>FD

EXAMPLE:
You are logged onto drive C and want to find
all duplicates files on drive D and want the
output to be in black and white.
C:>FD /d=d /bw


USING FIND DUPLICATES

Once Find Duplicates has been evoked, as described in "GET-
TING STARTED", the program will perform the following tasks:

* Search the specified Drive for all
subdirectories.
* Search each subdirectory for all files.
* Sort and store all files.
* Find all duplicates files.

While Find Duplicates is doing the above, the number of files
found is displayed on the screen.

After finding the duplicates files a display screen will ap-
pear. On the screen the duplicate files are displayed,
separated by a blank line. The following are the keys and ac-
tions that can be taken.

KEY ACTION
Down Arrow Move highlight bar down one
file.
Up Arrow Move highlight bar up one file.
PgDn Move highlight bar down 18
files.
PgUp Move highlight bar up 18 files.
Home Move highlight bar to first
file.
End Move highlight bar to last
file.
T Tag highlighted file for
deletion.
U Untag highlighted file.
P Print duplicate files to
printer.
V View highlighted file using
LIST.COM
F1 Display Help Screen.
F10 Erase tagged files.
ESC Exit Find Duplicates.

Once all the duplicate files have been tagged, depress the
F10 function key. You will be asked if you are sure you want
to erase the tagged files. If you depress "Y" the tagged
files will be erased, a screen will appear listing the number
of files that were erased and the amount of disk space recov-
ered, and the program will be terminated.

That is all there is to Find Duplicates. It was designed to
be easy but powerful. I hope you enjoy this program and put
it to good use.

OTHER PROGRAMS

I have used many Public Domain, Shareware and Commercial
software over the years. In appreciation to all those authors
of Public Domain Programs I have written several Public Do-
main Programs. They are:

EzDoss:
EzDoss is a Dos Shell. I have used many Dos
shells over the past years. Each program has sev-
eral features that I really enjoy. I decided to
write a Dos Shell that put most of those features
into EzDoss. EzDoss is both Menu Driven and has
"Quick Keys". Some of the features that EzDoss
has are:
* Tag files either singulary, all at once, or
by pattern.
* Copy, delete, move, rename, print or view
tagged or highlighted files.
* Include or Exclude file from being displayed
by a user defined mask.
* Edit an existing Ascii file.
* Invoke an Ascii text SideKick type editor.
* Locate all files using a user defined mask
for on a given drive.
* Print a tree of the specified disk drive.
* Format a disk without leaving EzDoss.

I am sure that once you try EzDoss and discover
all the power and ease it has this will become
an indespensible program.

Lima:
Another type of program I used reguarly are
text editors. The ones I used are either too
simple or too complex. I am used to using the
text editor that comes with Turbo Pascal. I
also bought Turbo Professional 5.0 which is a
set of over 400 Turbo Pascal routines that do
just about everything you can think of. I
wanted to write a program that uses many of
Turbo Professional routines and I had Turbo
Editor ToolBox so I wrote Lima (a bad pun on my
last name). Some of the featurs of Lima are:
* Dual Windows. Two files can be opened at the
same time. Windows can be zoomed, rotated or
switched between files.
* Buffering. Blocks of text can be copied or
moved from one window to another.
* Macros. Macros can be defined, and written
to a disk file.
* Keys can be redefined to key sequences of
your choice.

CopyCon:
I have written my share of short batch files us-
ing the "Copy Con" method. If I had a dime for
every time I goofed and had to start over, Donald
Trump would be borrowing money from me! I decided
to write a program that would replace Copy Con
and cleverly entitled it "CopyCon". CopyCon is
evoked the same what Copy Con is except there is
no space between Copy and Con. For example:
A:>copycon test.bat
This would evoke CopyCon and create, or load if
test.bat is an existing file, the file test.bat.
Copycon allows for backspacing, inserting and de-
leting lines, centering of text and graphic boxes
to name just a few options.

CopyCon IS NOT a text editor but a tool to use in
creating small batch files.

I hope you enjoyed Find Duplicates and please do not hesitate to send
comments and praise to me.


ABOUT DATA ACQUISITION INC.

Data Acquisition Inc. is a company that manufactures a micro-
processor based CMOS unit which can store information based
on events and time.

One of the products designed around the unit is a traffic
counter called MicroCounts. The MicroCounts unit can count
vehicle actuations, classify vehicles, or determine speeds.

This microcomputer unit can be adapted for various uses, such
as counting objects passing a given point (people though a
gate).

Data Acquisition Inc. will also write custom software. The
Public Domain Programs listed above is an example of the
quality and thought that goes into programs we develop.

If you think you have an application for our microprocessor
based unit or need custom software developed, please contact
