Freeing up space on startup disk

Hi,

I've been getting a message stating that my startup disk is almost full and I'm not able to open up two applications at the same time. My available space is about 250-300 mg so I delete a lot of files plus all the languages except for English. Now I have 6 GB available space so that's great. Ten minutes later it's back down to 300 mg available space. nothing has changed!

Any help would be greatly appreciated.

Thank You,
Jim

It's not uncommon for OS X to need/use 10GB or more of free space for temp/swap space. So, that's what happened.

have you tried to partition your hard drive? if so - it happened to me - and failed i could just reinstall lion
