Fast Duplicate File Finder Identifies Extra Copies

One of the more tedious tasks in cleaning up your computer to reclaim hard drive space is finding and deleting duplicate files.  Today we look Duplicate File Finder from MindGems, a free utility for finding and getting rid of the extra baggage.

Using Duplicate File Finder

This works with Windows 98 through Windows 7 so is a great way to clean up new and legacy systems.  It has a nicely laid out interface for scanning and identifying duplicate files on a single computer or an entire network.

    What if the duplicate has a different filename? Will it still identify the duplicate?

    Not working well for me. Ran it a couple of times with 0 matches (inconceivable!).
    Copied some files to another folder so I knew there were duplicates. Ran it again and it then found 30000+ duplicate files, a majority being temporary internet files of 0 byte size.
    Cleaned those up so I could have a fresh list to work from and now it’s back to finding 0 matches.

    Sorry, this one’s not hanging around.

    Yes, I tried it out myself, it found two images which were the same, but with different file names.

    I think it should be mentioned to handle this and any other duplicate file cleaner with a lot of caution. You could end up, as a friend of mine did, with a massive amount of file and shortcuts being deleted. At the very least you need to check carefully just what is about to be deleted.

    Mike J – there is an option to skip zero length files.
    Alan W – there is an option to protect system files and it is ON by default.
    The tool is extremely fast and works really well. I love the preview option.

    Cheers.

    I know software which has all described features but looks much better than this one.
    Duplicate Checker – http://www.duplicatechecker.com
    In addition Duplicate Checker has functionality for working with duplicate photos and images – preview bar and thumbnails bar.
