Compiling a build:

You will need to target the 10.7 SDK because Liten depends on a deprecated API calls.


The original project was started by building off of some sample code. The core algorithm of finding duplicates was built from this Python code:

Essentially, an md5 checksum is only performed after the size of the file matches a key in a hash. This makes for a pretty efficient tree walk.


You can download the application without compiling it here:


  1. Updating the deprecated API calls to 10.8
  2. Fixing various UI bugs
  3. Getting a better sort in the UI for human readable duplicates.
  4. Would love to do a folder merge.
  5. Better bulk delete
