I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Auslogic Duplicate File Finder is not can get it here
The problem with the duplicates is that you need a solid strategy of what to keep and where to keep..if you have something like a lot small files and you need tagging then a solution i found some years ago was Library.NET especially the Firebird "combo"...
You store all your files into single files (can be several Gigabytes in size) and you have a lot tagging and indexing...

You have to be careful about deleting what appear to be duplicate files.  Some programs will only look in certain places for things like 'dll's and if you delete the copy they're looking for, they won't run even if there are other identical copies elsewhere on the disk.

I am a programmer and wish to integrate the tool within my software, therefore I wanted to look at some other tool as to what they provide. This what you all are mentioning about system files is essential information, Thanks. Is there any specific algorithm that I can use to pick only data files.
eg: PST/Zip/images are generally duplicated

The best program for deleting duplicate images is DPEG
Use it in MD5 Hash mode for exact matches.
There are many other fuzzier modes.

It's effectively freeware unless you want to use the database feature.
