AHH! What do I do??
Ok...I'm currently using a Windows Vista and I'm currently defragmenting my PC with Defraggler to get more than just 40 GB of free space, but whenever I run it, my free space decreases, 1 GB at a time!

I dunno what's happening, but suddenly a bunch of fragmented files popped up in a cluster, and I lost 20 GB!!!!!

I got most of my space back by deleting system restore points, but now that I defrag again, the space goes down once more!!!

Any ideas what's causing the problem? Anything right now would save me a headache!
