    Gemini 2.0

    The intelligent duplicate file finder for your Mac

    I don't know of any great free ones. But you could run Gemini a couple times without upgrading it. It works really well. Then if you find it worth it, could upgrade.

    Mike is right. If you're looking for some free solution, Gemini 2 trial can clean up to 500 Mb of space.

    The new and improved file automator for the Mac

    This is my other favorite. I have this running all the time and it auto cleans up duplicates for me. Same as Gemini, you can do quite a lot without paying for it. I found it very useful and upgraded after a while of using it.
