Program that finds duplicate files

Is there a way or program that searches a given drive or given directory and it's subdirectories for duplicate files?

As far as I know, I often find this kind as a feature/function on cleaning software/free up disk space software or software utilities. The cleaning/free space tools often has this kind of function to find duplicated files so the user can delete it to clear space.

this is one example, but paid version

I'm sorry I can't find the free version, hope you can find one, or maybe another member can direct you to it. Just try google it, there's plenty out there

oh, before googling for it, try looking on TS download section, maybe you can find one

I use Auslogics Duplicate File Finder. I couldn't find it here in the downloads section, but here is another link http://www.auslogics.com/en/software/duplicate-file-finder/

Or you can even try this http://www.techspot.com/downloads/425-complete-cleanup.html

I use/like Duplicate Cleaner (free version, of course! )

after read your another post at
http://www.techspot.com/community/t...ve-or-given-directory-for-large-files.189315/

several cleaner program/utilities also have another function/tool to locate large files and also the type of files. But, mostly I found this packed in utilities program.

for example (it's paid version)

Use a great deal of caution before deleting any files that appear to be duplicates. Many programs have the same file in their folders as they load their own copy. What appears to be a true duplicate in most cases is not. In my opinion, there is little use for a program that finds "duplicate" files. Many inexperienced users delete necessary files and get in to a great deal of trouble. Unless you are intimately familiar with the dups, do not delete them.

Directory Report is very fast in finding duplicate files

It can also generate many reports

I'm facing the same dilemma regarding duplicates and had enough. I'd like to suggest the tool that works for me, its called "Duplicate Files Deleter" and uses md5 searching which is effective.. I've been using it for awhile to hunt down and delete those duplicates, hope it helps...
