    Hi -
    I am trying to free up hard drive space on my MBP.
    When I go to About This Mac > Storage, it shows that I have 35gb+ of video.
    However I have no idea where these could be.
    Could anyone suggest how I can find these files?
    Also does anyone have any general tips about how to find/manage files? I am not getting that far with finder - I have only found about 25% of the allegedly filled space - where is the rest of the files likely to be?
    Many thanks,

    Download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

    If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive.
    sudo /Applications/
    Another option is to use this terminal command
    sudo du -d 1 -x -c -g /

    I prefer to redirect it to a text file (this puts it in your Documents folder
    sudo du -d 1 -x -c -g / > ~/Documents/du.txt

    Like the sudo /Applications/ command, it will scan all directories, but produce a text file as opposed to showing the results in a window

    If you're wondering what "Other" category in the storage tab is about, this may help explain: For space issues not explained by the above, there are a few things you can try, some of which may or may not apply: Here are a few resolutions found by others with the same question: Freeing up drive space in Mac OS X

    To easily find files you can use a free app called EasyFind (AppStore).
    To find big files easily on your MBP, you can use DiskWave (

    Hi, thanks for the advice, I verified the disk and received a bunch of warnings:

    "Disc utility stopped verifying "Mac OS X
    This disk needs to be repaired using the Recovery HD. Restart your computer.. etc
    The message lists:
    - Volume bitmap needs minor repair for orphaned blocks
    - Invalid volume free block count
    - The volume Mac OS X was found corrupt and needs to be repaired
    Error: This disk needs to repaired us…es window appears, choose Disk Utility."

    I am backing up now and will follow the above instructions.
    Is this anything serious and would it explain the "missing" disk space?

    Could be your hard drive on its way out.

    You can use this chance to speed up your Mac greatly with an SSD.

    Try something called DiskWave.

    It will show you files BY NAME and by size. Largest size above, smaller sizes below.

    Quite different from the other apps that show "block graphics", with no names to help you understand what-is-what.

    Thanks - when time machine backs up does it normally only make an incremental back up, rather than backing up the whole drive? I never really noticed before..

    First time is the whole machine, the hourly backups are incremental.

    You can use Disk Utility X it breaks down where everything is and what it is.
