Hard Drive and free space

[kiddo1972]

This is not really a problem compared to real problems people have on here but has anyone ever seen your hard drive free space fluctuate without making any changes? Mine goes up and down between 5 to 10 gigs every two to five days on my laptop and my desktop.  Should I be worried?

My specs on the desktop                                     Specs on the laptop
320 GB Seagate Barracuda SATA                         120 GB WD BEVS ATA
Nvidia 8600 GTS                                                    Nvidia GForce 7150m
4GB DDR2 RAM 667 MHz                                       3GB DDR2 soDimm
AMD Live 64x2 4400 2.3 GHz                                AMD Turion 64x2 2.0 GHz

Sounds like volume shadow copy/previous versions and/or system restore, saving new checkpoints/copies and deleting older checkpoints/shadow copies.

Yeah Thanks, I forgot about about that. It just seemed like a bit much and the fact I had never seen it fluctuate in such large amounts before. So it had me kind of baffled.
