An app for Windows for hunting down and eradicating multiple copies of files?

December 13, 2009 4:30 AM

Is there an app for Windows that you know of for hunting down and eradicating multiple copies of the same files?

Let's say I have a 1TB drive (I do) full of junk (I do) and much of that junk has duplicates, triplicates, and octuplicates of the same files in miscellaneous folders.

I'd like to find a program that I could leave running and it would scan the drive for these multiple copies and perhaps erase them for me, or at least allow me to do that later.

Know of any?

Duplicate File Detective has a fully functioning 15 day trial, $40.00 to buy. I use it and find it to be fast and accurate.

I use this one. I must warn you that I've never scanned a whole drive (much less a 1 TB one) with it, so I cannot guarantee you it will not crash or misbehave in some manner. It has always worked fine for me, though.

Just don't forget to specify "Contents Only" or "Contents And Name" when searching for duplicates, else you may delete files which are not actually identical.

I've had good results with Fast Duplicate File Finder. It's freeware.

I use an older version of Beyond Compare. It has enough fine-grained options to handle any of my needs (e.g., same picture with a different name, html files with different extensions...) The current version has a free 30-day trial.

I've been using Easy Duplicate Finder, which is free and works quite well.

Double Killer is great. I have the pay version (which really is better), but the free version is also great.

CloneSpy is my go-to dedupe tool; it's freeware and very flexible. (I love Beyond Compare as well but as the name implies it's meant for comparing files/hierarchies, not for finding and nuking duplicates across an entire filesystem.)

I second Lazio. I am yet to find better alternative to CloneSpy
