    Hello all,


    I have so many duplicate music files on a hard drive of mine and I was wondering if someone knows a good, preferably free software I could use to find the duplicate files and delete them.

    I am using a MacBookPro running OS 10.8.4. I have my music files backed up on 1 terabyte removable hard drive. I'm not using Time Machine, by the way.

    Thanks, all!:apple:

    I'm not sure what software to use, but I do have 2 important suggestions:
    1. Make sure you have a complete backup of your system before you start removing duplicate files.
    2. Make sure you only scan user files for duplicates.

    Hi,

    Thanks for your suggestions.

    What's the difference between user files and other files?

    You get user files mostly the ones you create - music/films etc..
    And get system files that the system needs to run correct the OSX or applications and without these files can cause problems. Therefore if you run through the system files it could delete files that your system really needs to stay stable :)

    OK. I thought as much. Yeah, I would only be scanning files I have on a removable hard drive; all music files.

    If you only scan the external hard drive you'll be fine I'm not sure in the program you would use though :)

    Gemini seems to be a frequently recommended app for removing duplicate files, but it's not free, i.e. $10 in the Mac App Store - :)

    Are you happy/satisfied with the software?

    I had to buy a new External Drive for Time Machine (old drive had a power failure) and noticed my 1TB Internal HDD was almost at capacity.

    I tried doing a size search but other than some newly imported movies, it seems the majority is the mass of smaller files (like Music and Photos) that I have been importing.

    Trying to find a decent application to find dupes...and possibly delete the=m.

    THANKS!

    I have Gemini (bought it as part of a bundle) and it didn't work at all and the developers never responded to my email. Is there another option?

    You could do this for free in terminal. Check out find and md5...

    program to delete duplicate files

    If I move a file from one folder to another, iDrive will recognize the moved file as a new file because it is in a different directory. Is there a way to delete the old file automatically?
