Possible CCleaner + Defraggler Problem?

Hi, sorry if I am not posting in the right place. I am doing a Defrag, using Defraggler, which it says "Fragmented Files (15.4GB)". I have done many Defrags in the past with no problems. And I am also running a CCleaner "Wipe Free Space". which is currently at 40% of a 1TB Hard Drive.

I was checking my hard drive space after an hour of running both, and it seems that my (C:\) Hard Drive has went from around "750GB Free of 918GB" to "437GB Free of 918GB". And it keeps going down!!! I don't think I should stop it, because it could be normal, however I am not sure if this is normal.

Here's a bunch of specs if you needed them:

  • Windows 7 - 64-Bit
  • 4GB RAM
  • 1TB Hard Drive

Can anybody please help me?

PS: It too me like 3 minutes to type this, and in that time it has gone from "437GB Free" to "432GB Free". So this is rapidly gaining space on the Hard Drive.

Correct me if I err, but I read that you are defragging and wiping simultaneously. If so, stop the defrag and let the wipe continue until finished. You will regain the lost space.

why are you wiping the drive?

pro-tip only wipe if selling or really require it. You gain nothing from doing it at it will reduce the lifespan of the drive
