I keep getting the message that my startup disk is full. I tried deleting a lot of files and emptying my trash, but that didn't help. When I look at how my memory is being used, it says that I have "Zero KB free out of 499.25GB", and this is how it is being used: Audio- 43.93 GB Movies- 9.56 GB Photos- 1.38 GB Apps- 4.58 GB Backups- Zero KB Other- 439.8 GB So, I'm assuming that "other" is the problem, and I can't figure out what "other" is. I've tried downloading OmniDiskSweeper, but because my Startup Disk is full and I can't seem to make more space by deleting things, I can't download it. So basically I'm in a very aggravating pickle, and I would really appreciate some help.
