    Hi all,

    I have a 09 Mac Pro, 256GB SDD fitted as the main OS drive, with 3x1 TB HDDs for work projects/music&movies/backup (in that order).

    When i was bouncing a music track down today, I was told there wasn't enough room on the SSD - bearing in mind i bounce my tracks down to one of the HDDs, i'm a little confused.
    I've looked on the SSD and found 4 folders; Applications, Library, System, Users. Info on the Users tab, it shows to be using 140GB, but when i click within this folder - there's barely anything in it, the biggest folder being Pictures which has 2GB in it.

    Where are all these files that are clogging up my system drive? I've emptied the trash - it's not there. I've cleaned with Onyx, but i still can't seem to locate this 100+ GB of phantom data..

    Can anyone give me any ideas?

    Download and run OmniDiskSweeper (its free) It will provide a sorted list of your files/folders and show you where all your space is going. The app includes system and hidden folders as well as user folders

    Thank you very much - downloaded and will give it a sweep. Intrigued to see how i can't see 100GB.

    Will update shortly,


    Turns out most of it is based in 'Users - Library - Application Support - Adobe - Common'.

    This has over 100GB of audio files. I don't really use Adobe.. Most of my work is done through ProTools and Logic. Am i right in thinking this is just cached and i'm ok to delete it..?

    You may have found the exact problem I discovered a few months back...Adobe was caching render files hidden in the Library and never deleting them as one had to go into preferences of the adobe program to do it. As far as I know adobe doesn't have audio loops (like Apple Studio did) so there shouldn't be anything that is necessary (or even useful).

    If you used Premiere Pro or Audition or Encore with any regularity For a while it could be vestiges from projects.
