What is taking up all that space?

[hafr]

According to Disk Utility I'm using about 240 GB of my hard drive, but my Time Machine backup is only just under 90 GB and the only two folders that I've chosen to not be included weighs in at just over 30 GB. That means I've got 120 GB unaccounted for that not even Time Machine thinks is important enough to back up, but I have no idea where these files are hiding... I've tried Clean My Mac, but it doesn't find more than roughly 500 MB that can be cleaned.

I've verified the disk, I've checked it's permissions, I've rebooted... Anyone got any idea of what's happening?

For space issues, there are a few things you can try, some of which may or may not apply:

• Begin by restarting your computer as a first step. This sometimes resolves issues.
• For Time Machine users on notebooks running Lion, space may being consumed by Time Machine local snapshots, which can be disabled.

• Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.
  
  
• Use OmniDiskSweeper, JDisk Report, Disk Inventory X or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.

That was it. 114 GB used as backup... Thanks a lot!
