Find Duplicates - discover duplicated files
Find Duplicates was written to allow you to control your disk space usage
by discovering files that are duplicated and, should you so wish, deleting
one or more of these duplicates. There are many ways in which duplicate
files can be deposited on your hard disk, for example programs which
don't check to see if you have a particular DLL installed and install
their own private copy in any case, or other programs that install a DLL
in your \Windows directory when it is already in \Windows\System32.
Find Duplicates scans one or more disks on your system to find multiple
files, in a two-phase process. First it scans all the directories and sorts
all the files it finds into size order (files HAVE to be the same size to be
identical!) You can limit the scan to one directory tree, if you wish. It
then compares files of the same size to see if the contents are actually
identical, and lists identical files by size order. You can then double-
click on any file to examine its details, and optionally delete it.
This process can take some time, so Find Duplicates will first perform
one of two preliminary checks to see if the files might actually be identical
without having to actually examine the whole file. By default, it checks the
date and time stamp of the files, and only compares the files byte-by-byte if
the timestamps are the same. But it is possible for two files to have the
same contents without having the same date/time stamp, so you can enable an
option whereby the first 512 bytes of each file are checksummed. This
improves the recognition of identical files, but it is slower, and since it
involves a file access, the file's last access date will be altered. By
default, the timestamp, not the checksum comparison is selected. In either
case, the filename is ignored, so simply renaming a file will not hide the
fact that it is a duplicte. You may be rather surprised to discover what
duplicates actually exist in some popular office suites!
Usage:
Extract FindDupl.exe from the zip file to a convenient location, and run it!
You will be presented with a dialog box showing you disk drives, with your
local hard disk drives selected. You can optionally enter a file
specification such as *.EXE and a directory specification such as \windows
to limit the search. Note that if you enter a directory specification, then
only that directory will be searched on each drive (e.g. c:\windows,
d:\windows and so on). Press the Start Search button to find duplicate files.
There is a status bar which will keep you informed on the progress of both the
directory scan phase, and the file comparison phase. Once the main list box
has filled up with file names, you can double-click on a file name to get
a pseudo properties dialog box (actually written in Delphi, not derived from
the system right-click -> Properties box). You will see a delete button which
allows you actually to delete the file.

Notes:
The program is written with Borland's Delphi 2.0, and most of the source is
included. You do not need access to Delphi 2.0 to run Find Duplicates. You
will need other Delphi units (not included in the archive) in order to
re-compile Find Duplicates. The program has been tested on Windows 95 and
Windows NT 4.0.
