    When checking out my "About THis Mac" section, under storage, I have over 13 gigs of "Other" which I can't account for. How would I discover what it might be? And it's def. not the system because it's 13 gigs of the 121 gigs (out of grand total of 128 GB).

    THis is the new 13".

    I have 21Gb of Other! I'm guessing its all the system etc.

    "Other" would include the operating system, any virtual-memory swap files on your drive, etc. In other words, "other" is all the stuff that enables your computer to operate.

    Those virtual memory files can be large - usually the same size as the amount of RAM in your machine. For instance, my 2010 11" MBA has a 4.0 GB vm file in /private/var/vm/sleepimage.

    Also, any application data files will appear under "Other". I use Parallels to run a few Windows programs, and my Windows virtual machine file is approximately 40 GB in size, which explains why my "Other" category shows up as 56 GB in size.

    Hm, but isn't that what the discrepancy between the "usable" storage space and actual storage space is? Isn't that difference for the system and whatnot?

    For example, I got the 128 GB, but only 121 GB is usable. Then I suppose my question is, what is taking up 7 GBs from 128 to 121?

    It seems like the right amount for formatting, but from SL onwards it was counted correctly so a 128Gb drive would have 128Gb or usable space.

    Hidden built in Lion restore partition? I wasn't paying attention to the pre release lion stuff but I recall mention of apple implementing this on the new macs.

    Can you be rid of the partition?

    it's file extensions that aren't can't be categorized as movies,photo's,music, etc.

    i had a large MKV file that I deleted and it brought "OTher" down because the OS didn't recognize it as a movie file.

    More than that.
    Don't get rid of it, it's less than 700 mb, you will be glad you don't have to wait through a 4-5 hr reinstall later.
    Good call, it's still not a very accurate representation of what is taken.. if it only recognizes native file types :/

    Don't. It's your only backup on the MB Air.

    Part of the 7GB's is lost to the SSD for garbage collection.

    Large "Other"Amount

    I'm also seeing a large portion of my SSD being taken by "Other" files. Does 48GB seem too much?

    Use Disk Inventory X or Grand Perspective to see how space is being used on your drive.

    I noticed this earlier, I've got 121Gb of other and can't rid off it even after indexing.

    Would anyone have any suggestions on what it could be and getting rid of it?

    I've tried programs suggested above and it doesn't help and AppleCare were useless
    Otherwise thinking of reinstalling Lion

    You're saying you used one of the apps I mentioned and they show the 121GB as "other"?

    No. Strangely, that app states I have about 100GB free but Mac OS fails to say the same and claims my HD is full in the 'about this mac' section and with constant reminders when I try to do anything

    I've know for certain it can't be full so I am stumped with how to fix it.

    Is there a feature like 'system restore' for windows on Macs so you can turn the computer back to previous settings/installations?

    Have you emptied your Trash? Have you restarted your Mac?

    Use Disk Utility to "Erase Free Space" that will probably fix it.

    EDIT: Nevermind you can't use "Erase Free Space" on the new MacBook Air's.

    Done this, restarted and allowed it to index but still nothing as changed. I am just gonna reinstall Lion i guess then.

    Think I will try out the Lion Recovery Disc Assistant!

    If you're wondering what "Other" category in the Lion 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:
