My start up disk is full, yet I haven't loaded any new applications and I have removed my files onto my external hard drive and deleted the trash. I wonder if it is something to do with timeline or back up, if so, where would this be and how can I find and delete them, and stop it from backing up?

    Which version of OS X are you running? If Lion or Mountain Lion, go under the Apple menu to "About This Mac.." and then click "More Info..." and you'll see a box pop up with you system information. Click on the Storage tab and take a screenshot of that and post it hear, using the little camera icon at the top composition bar to insert the photo:

    Hi Clinton


    So, I now don't have the Internet, so I can only reply by my phone.


    I'm running off Mac OS X Lion 10.7.5 (11G56)


    My apps only take up 8.4gb

    Photos - 33GB

    No backups, they are all on my external drive, as I didn't understand it.

    The main one is 'other' yellow 50GB.


    What's this and how do I start deleting stuff, I've already taken a lot of my work off. I'm a designer but do store

    Most of my freelance work my hard drive.


    It's happened more since my husband started using it

    For his wedding photography, but he takes off the photos when he's not editing them.


    The photos that are on there are ones we are editing right now.

    "Other" is just that - anything that doesn't neatly fit in the Photos, Movies, Audio, etc. categories (see -> http://pondini.org/OSX/LionStorage.html and http://pondini.org/OSX/DiskSpace.html).


    Hopefully Pondini's articles will help out.


    Good luck,

    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:


    iPhoto Empty Trash


    Then reboot. That will temporarily free up some space.


    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.


    If you're using Time Machine to back up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.


    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.


    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.


    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.


    Proceed further only if the problem isn't solved by the above steps.


    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.


    Back up all data now.


    Install ODS in the Applications folder as usual. Quit it if it's running.


    Triple-click the line of text below on this page to select it, then copy the selected text to the Clipboard (command-C):

    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

    Launch the Terminal application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.


    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.


    The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.


    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.


    When you're done with ODS, quit it and also quit Terminal.

    Thank you for this I will try some if that tonight.

    I have deleted Alot of my files (or moved them to my hard drive)


    Even though I have deleted about 25gb, the top bar which says about the usage hasn't really changed, still saying

    20gb left of 120gb. I have emptied the trash and restarted.

    Will look again tonight when I get home and try some of your point.



    Thank you

    That's normal and expected. What matters is not the amount of free space shown in the Storage display, but the amount of avaialble space shown in a Finder Info window. It should be at least about 9 GB.
