I was just wondering if there were any good free 3rd party programs out their that can do the same job [hopefully better] than Disc management for windows. There's some unallocated partition on my friend's drive i can't seem to get rid of. There are also two other partitition and one of them is near full.

Arconis Disk Director, or Partition Magic, perhaps?

Is this computer one that you built yourself, or one from Dell, HP, or whatever?

Oftentimes, there's a recovery partition with stuff on it that could be what you're seeing.

Acer. It doesn't have that partition. This was a vista but her cousin's installed xp on it and did a bunch of wierd partitions now there's 3. One odd thing about it, one has her system files and what not, the other is where all of her documents and settings on her disc top loads from. and the third is just some unallocated space. The drive with her documents and settings is low on space and I'm thinkin to just destroy the partition and add it on to the drive with little space.

gparted.

Run it from a LiveCD so yiu're not trying to edit partitions you're actually using at the time.
