[Defraggler chewed up all free disk space]

After reading comments on other threads, I disabled System Restore and hence deleted all the restore backups and it's sorted - I now have 116GB free space back.

So why is Defraggle causing this? The disk space was fine until I ran Defraggle. Each time it ate more disk space. After running it four times it ate around 100GB.

I've just installed TreeSize Free and it shows I have only 1% (1.6GB) free. Yet the size of C: files & folders add up to only 109.8GB.

I do have another partition on the drive, but that is only 3.6GB.

So where is my other 112GB gone?

I too am having the same problem. I had around 40% free space on my 222GB disk. Over the last few weeks it has now decreased to only 1.6GB free! I've just realised that it is Defraggler causing it as after I ran it again last night.

I've just joined this forum for help on this matter.
