Duplicate Icon Processor v2.0
Copyright (c) 1991, 1992 by Keith Ledbetter

DUPICON is a program that will go through your drives and find all
exact matches of icon files. I wrote this program because my Icon
collection has grown to approximately 1800 icons, and trying to weed out
all of the duplicates by hand is quite tedious.

The program was a "quickie", so I'll say up front that you are not
going to be overwhelmed by beautiful screen displays , but it is
functional and has been exhaustively tested. v2.0 will now support
up to 10,000 icons in one search (this number may be smaller depending
on your available memory at run time).

When you first run DUPICON, it will prompt you for where you want
the program to search. The options are:

[A] All drives [B] Current drive [C] Current directory:

[A] will search for .ICO files on all drives (C: - Z:) and in
all subdirectories.

[B] will search all subdirectories on the current drive only.

[C] will search the current directory (and all directories under
it). This option is handy if you have one master \ICON\
directory with subdirectories under it.

Next, you'll be prompted for deletion options:

[A] Prompt for deletion [B] Just list them [C] Auto delete:

[A] will prompt you for each duplicate found, asking you which
file to delete.

[B] will only display the duplicates found to the screen.

[C] will automatically delete the second icon.

How it works

DUPICON first scans the appropriate drives and directories to build a
table of all .ICO files found. Next, it reads each .ICO file and
calculates a 16-bit CRC of each file. Lastly, it goes through all .ICO
files where the CRC matches and does an exact BYTE-for-BYTE compare to make
sure that the two icons are exact matches. If they are, you will be
prompted to delete one of the icons (if you asked DUPICON to prompt you).

That's All!
