logoDuplicate Files Finder Portable 0.8.0 has been released. Duplicate Files Finder lets you find and remove duplicate files from your storage devices. It's packaged in Format so it can easily integrate with the Platform. And it's open source and completely free.

Update automatically or install from the portable app store in the Platform.


ScreenshotDuplicate Files Finder is an application which searches for duplicate files (files which have the same content, but not necessarily the same name) and lets the user remove duplicate files, either by deleting them or by creating links. The search is very fast compared to other similiar programs which use hashing algorithms.

I have tried many duplicate file programs that take forever, but this one just screamed through it. Very nice and simple but very effective.

When Satan is knocking at your door, simply say, Jesus, could you get that for me?

Most hash a full file and compare hashes. Which is a bit disk and CPU intensive. This one reads in bytes from the beginning of the file and compares them directly, which is much more efficient.

Sometimes, the impossible can become possible, if you're awesome!

To clarify what John said, it will do a byte-by-byte comparison and then immediately stop if it finds a difference.
A hashing requires reading the entire file regardless of them being different, this only reads as much as it needs to until they it notices they differ.

Going to get some stuff off an old XP computer before trying out linux on it, given the lack of support XP has now.
So will be putting this tool to good use.

If at first you do not succeed, use more sticky tape.

All it does for me is show me which files have the exact same file size. It doesn't actually check that they are the same—unless I am doing something wrong, which is always a possibility.

I downloaded an anime wallpaper dump from Reddit (/r/anime) and I noticed there were duplicates. For small, single-use tools like this, I turn to PortableApps, even to be used locally. So I scan the folder, and sure enough there are about a dozen files found with the same size. 8 were, in fact, duplicates, but 4 were not. They were nothing alike. They were merely the same size. So a byte by byte comparison did not happen.

Hello, great app, I like it very much!
However, I can't scroll in results window. Neither with focur nor without it (I use Tordex Wheel and I'm able to scroll unfocused windows)
