[QUOTE="jamespickett, post: 823286, member: 93500"] Once your RAM is full, the computer uses "virtual Memory" (it writes whatever it needs to the hard drive instead of using memory)... When you are forced to RE-boot, it purges the data it has stored temporarily on your hard drive, freeing up the space again. (this is why photoshop has a "scratch disk" option, so you can use an external hard drive or second internal and not the machines primary drive.) To the gentelman that started the post... Buy an external, use it... I always used to leave at least 20-30 GB free on my HD "just in case"... these days everything goes on externals unless i am working on it right now. I've been using Macs for 15 years... and this has always been a problem. [/QUOTE]
