    Hello everyone -

    Is it possible and safe to move applications from the App Store to external hard drives or USB flash sticks? If so, is there anything that needs to be done to keep everything working correctly other than to just drag the icon from the Applications folder over to where I want it to go? I'm short on space on my MacBook Air and would like to move some larger apps off of my internal drive if possible.

    Shouldn't be a problem. They are required to be fully contained, and should only leave preferences in most cases on your internal drive. Poorly written ones might react badly to being moved, but most should be fine.

    Of course, and this isn't universally true, apps are rarely what take up a lot of space. You may find you're better served trying to move media off instead.

    Sorry to revive this old thread, but does anyone know if I move apps to an external or optibay hard drive, will they still be updated? I would think they would, but would like someone who has first-hand experience.

    I used Carbon Copy Cloner to throw my entire Lion/Apps over to a Pegasus R4 unit in Raid 0(450Mbps write/read) and when I went to run Photoshop from the R4 it loaded so fast I couldn't believe it. I only have a 1TB HD in my 2011 iMac but I couldn't get the iMac to boot to the R4. I may have to do a fresh install of Lion or something...still looking into it. I haven't had a chance to do the updater but I see no issue why it wouldn't update being on a different drive.
