Hello and thanks for the question.

There are indeed a number of programs that do exactly what you are
looking for. A popular option is called “Check Identical Files” and
can be downloaded for free at:

I downloaded and tried this utility and found the user-interface to be
very intuitive and easy to use.  I was actually surprised to find the
number of duplicate files on my hard-drive! I ran a couple of cursory
tests: (1) creating a duplicate file with a different name, and (2)
creating a copy of a file with a slight modification.  In the first
case the program successfully detected the duplicates and in the
second case the program correctly did not identify the files as

program called "DeDupe" which is available for $24.95 and can be
located at:


This one seems to have a few more capabilities than the shareware
version, so depending on your needs this might be a better product. 
There is also a trial version that is available for download on their

This Q&A addresses some of the dangers involved in deleting duplicate
files.  Deleting duplicates is to be avoided in cases of system files

You can also try NoClone which features a byte-by-byte comparison
which compare file contents regardless file name and file time. And
smart file removal mark file by file name pattern, date, folder, size
and version. NoClone can be found at and was
recommended by ZDNet

That's exactly what "Check Identical Files" does. It was the first
duplicate checker that did byte-to-byte comparison, instead of relying
on checksums.

It also does this very fast, faster than any other duplicate checker I
know of. "Check Identical Files" has a very liberal trial policy: you
can use it at least 10 times throughout months or years (so not
limited to a trial period of 30 days). If you only check duplicates
occasionally, then use the trial period wisely :)
