I get getting an error that says "can't write to drive C out of disk space" .
This is a brand new computer with an 80 gb hard drive and in properties I
have used less than 10 gb.
Hmm, just a few wild guesses:
1) I saw a similar thing on a Linux machine just a few months ago. And
then it had ran out of inodes, which effectively means it has no slots
available for keeping the administration. Can it been that NTFS has a
similar thing? In that case having lots of small files will get the
disk full way before all space is used.
2) Can it have something to do with sector size and the average file
size. Again if you have lots of small files, you'll end up with a lot
of slack (unused space in a sector).
3) Are there multiple users on the PC? Are the other users perhaps
having a Recycle Bin that is full of junk?
Good luck
