"Other" just ate my hard drive When I woke up his morning, I had >80 GB of free space on my hard drive. Over the last four hours, in which I wasn't even around, something filled my hard drive completely. I would attach a screenshot, but there isn't even room to save one. 

I'm currently looking at around 210GB of 'other' on my 250GB HD - and I have no idea where it came from. It's always been fairly stable until today. 

I am, of course, deleting everything I can afford to, but unless someone knows of something huge I can nuke where 'other' is, I don't think I'll be able to get it down to a manageable size.

I have a Time Machine backup. If I restore to it, will it also contain this huge amount of 'other'? Or is there a better option?
There are many things that 'other' could be. This Apple KB article details what 'other' space is:

…but basically, there's not only one thing that it could be, or one thing that everyone's suffered from.

Your best bet is probably to run something like Daisy Disk or similar to find large files to delete. Alternatively, use Finder and search for large files sorted by Date Modified so that you can see recent files that might be taking up large quantities of space.
