    So, for a while now I have struggled with keeping space on my Macbook Air.

    The biggest things I have are my itunes and all my Sims 3 games, but yet I still barely have 30 gigs free. I can't figure out what is taking up all the space, and I have programs like DaisyDisk installed to help me out.

    There is nothing on this computer I can't live without that hasn't already been transferred, so I'm wondering if there is a way to just simply format my Air and erase everything off of it and start from scratch?

    Sure.... just command-r boot to recovery. Then start Disk Utility and erase Macintosh HD to Mac OS Extended (Journaled). Quit Disk Utility then click reinstall OS and wait while the ~5GB OS downloads and installs.

    At the end a setup process will run where you can setup a new admin account for yourself. This will give you a clean account with nothing but the OS installed.

    If you want to give this a shot first though, enter the command below in Terminal and post up the output. This will list all the root folders and the size of each in GB.

    Code:
    sudo du -d 1 -x -c -g /
