AcuteFinder - Find duplicate files
Click for larger image

Want to free up space and reduce clutter on your disks?

AcuteFinder will help you to find duplicate files on your system and delete them. It's simple, easy, and safe to use, and costs as little as $14 to buy.

AcuteFinder not only takes into account items like file name, size or timestamp, but reads through possible duplicates and calculates their checksums. This way, it is guaranteed that the files are really identical, and you can delete the extra copies with full confidence.

AcuteFinder can find files that have different names, like "my.doc" and "Copy of my.doc". Basically, if files are of the same size and have the same checksum, they are considered identical. AcuteFinder uses by default CRC32, a 32-bit checksum, but you can choose to use MD5 hash (128-bit) as a final step in file comparison for even more accuracy.

As easy to use as 1-2-3

Using AcuteFinder is easy — you just have to:

  • Define search criteria and press the Start-button
  • Review the list of found files, and mark those you want to delete/move
  • Delete or move those files!

That's all there is to it. You can select one or many files at a time, using the Windows conventional method of holding the Ctrl or Shift-keys while clicking with the mouse.

Alternatively, you can select all files listed using Ctrl-A and press Delete for fast cleanup of duplicate files. AcuteFinder by default retains at least one file from each set of duplicates, so you can rest assured that one copy will remain. See our Flash-demo on how easy it is to use AcuteFinder (800 kb).


AcuteFinder helps you to keep your drives well organized. It will pinpoint duplicated files and allow you to delete them, resulting in:

  • Less clutter
  • More free disk space
  • Faster virus scans
  • Faster spyware scans
  • Faster file searches and indexing
  • Faster backups, using less media
  • Less confusion!

Why use AcuteFinder?

AcuteFinder can help you to reclaim disk space wasted by all the extra copies of files, which is especially important on "limited" resources, like laptops and memory disks. Even though disk space gets cheaper every day, you need to keep your files well organized. Otherwise you will sooner or later, simply fill your disks with clutter.

Also, file sizes tend to increase with all the fancy multimedia presentations, music files, digital pictures, and so on. It can be VERY difficult to determine if such files are really identical, without a comparison tool like AcuteFinder.

Few examples

You can use AcuteFinder to remove files from old backups, that are replicated in newer backups. Just enter your new and old backup paths, and protect the new one, by right-clicking on it and select "Protect on/off". Then perform the scan. The resulting list will show you all duplicated files; just press Ctrl-A (Select all) and then the Delete button. All extra copies found in the old path will be deleted, but all files in the new path will remain. File that are different between the backups, did not show up on the list of duplicates, and therefore you keep the old version in the old path.

Let's say you have recently copied pictures to a CD or DVD disk for long-time archival. You want to be sure that the copies are exact and then delete the original from your hard disk. To achive this, just enter your CD/DVD path, protect it via the pop-up menu, add the appropriate path on your hard disk, and scan for duplicates. The resulting list will show you all duplicated files; just press Ctrl-A (Select all) and then the delete button. All extra copies found on the hard disk will be deleted, and the scan itself has verified that the copies were exactly the same.

Please note

If you are not familiar with file management, then AcuteFinder is maybe not for you. It does not automatically perform any deletes, but requires your understanding, interaction and decision making when operating on found files. Instead, we recommend that you seek the help of a qualified computing professional, and ask him/her to use AcuteFinder on your behalf.
