I ran the Erase Free Space program and it filled up my hard drive and now it seems to be stuck on Zero KB remaining on the Hard Drive. It's been stuck on it for a couple hours now. Also, I can't open any of my documents. I need some help, badly. Please!
Wait, it just popped up to 45 KB but it's taking forever. Should I just let it keep going?
If Erase Free Space seems to have completed yet stalled, try deleting this folder or file . . 
Oops Kroozer this is for Mac.

Note: Wiping free space can take several hours.

Yup, my big blunder. It's been a long day. Thanx.
CCMac uses the OS.X built in mechanism. It will probably leave a temporary file somewhere taking the free space when the process is interrupted. That is why in CCMac it is not possible to cancel the operation.
Let it run.
