    Hey guys, my MBA has a 128GB flash drive and apparently I only have 24GB left available so I went to investigate what is using 104GB of space and I can't figure it out. Stuff isn't making sense.

    If I individually measure the file sizes of each of the folders in my Home folder, it comes to about 18GB. But, if I ask for the size of the Home folder itself, it say it's 63GB. Huh? Is there some hidden folder in my Home folder that is taking up 43GB?

    That said, since there's only one user on this computer, where's the other gig? My Applications folder is only 8GB and that's it. I don't have any files on my computer other than system files that I'm aware of other than what's in my Home folder and my Applications folder.

    Is there any kind of app that will show specifically where my storage space is being used? I used a Finder window and searched All Files sort by size, but it uses very wide sizes and I can't pin it down. It also doesn't show me anything larger than a 1GB file so I need something more accurate.

    Any ideas?

    Its sounds like you could do with a disk analyser. try Daisy Disk in the App Store, or Grand Perspective. They will both give you a graphical representation of your drive showing you whats using space.

    Thanks very much! I just downloaded Daisy Disk! Looks like iCloud is taking up 18GB, my Gmail is taking up 27GB... it all adds up unfortunately. :(

    Just wondering, how is Gmail taking up 27GB?

    Probably saving the mail to the computer and not just keeping it on the server

    Doesn't Mail do this by default, to enhance searching?

    If you want to keep this feature you could go into gmail's settings (online) and set IMAP to only the last 1000 messages or so...

    If you're wondering what "Other" category in the Lion/ML storage tab is about, this may help explain:

    Check out Space Gremlin for analyzing disk space. It's my favorite!

    Here's a vote for WhatSize - been using it for years.

    20+ gigs free is not catastrophic, but if you see that going up in the future, you should take measures...
