Find duplicate files and clear the space
Find Duplicates compares the contents of every file in the folders you choose and shows the ones that are exact copies of each other. The copies you tick go to the Trash, and one of each file always stays.
Coming in the next version of AMWT Desktop. The download today is version 1.0.0, which has Data Recovery; it updates itself when the new version is out.

Find Duplicates
What it does
- Exact copies onlyFiles are compared by their contents, not their names, so a renamed copy is found and two different photos with the same name are not.
- One of each staysEvery copy except the oldest is ticked to start with. You can't tick every copy of a file.
- To the Trash, not deletedCopies go to the Trash or Recycle Bin, so you can put any back. A file that changed since the search is left alone.
How it works
Find Duplicates in three steps
Choose folders
Pictures and Downloads are suggested; add any others.
Find duplicates
Files of the same size are compared, first their start and then their whole contents.
Tick and move
Check what's ticked, untick any copies you want to keep, then move the rest to the Trash.
Good to know
What it can and can't do
- Hidden folders, app folders and photo libraries are left out, so removing a copy never breaks an app or a library.
- Files under 100 KB are skipped unless you choose to include them; they free very little.
- Near-duplicates (the same photo edited or resized) are not exact copies, so they are not listed.
