    In the past day something has taken up 260GB of space on my hard drive. I used daisy disk to find what it was and initially it just said it was "hidden space" then I found out that it was macintosh HD/.mobilebackups/ but i can access that folder to clean it out. the reason this bothers me is that those 260gb accumulated over the corse of a few hours. In the morning I had 400gb available and by the afternoon I had 200gb. So why is this happening and how can I clean it up.

    That is Time Machine local backups. You can just ignore it and if you need the space OS X will shrink the space used my local backups on its own. If it is bothering you , you can turn Time Machine off then back on and the space will be zeroed out.

    Turning local backups off can be a bad idea. It creates these backups when you are away from a Time Machine destination so if you accidentally delete a file you can get it back from the local backup. It does no harm to leave it on.

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

    FYI, even though the space is "consumed" it will be re-claimed by the OS if needed - and as a result does not show up when you do get info on your hard drive.
    i.e., if you have a 500gb drive with 150gb used and 260gb of time machine backups, you could then copy 300gb to the drive and it would work - the time machine data would be automatically wiped.

    My advice: just ignore it. You get the benefit of your otherwise unused space being able to get you out of the poo if you destroy/damage/overwrite/lose a file between time machine backups to external storage.
