Computer Space...

I was thinking of formatting this computer and was thinking about partitioning the main hard drive so it has JUST enough space for programs and the OS so I don't have to go through the torture of moving all my files to an external hard drive... (why I didn't partition my hard drive in the first place is a mystery to me)

I was thinking around 10-20 GB... Probably 20 GB... That's no problem when you have an 80 GB, 200 GB and a 320 GB hard drives, that last one being an external hard drive...

The OS itself already uses 2-3 GB and then there's everything else...
