Holy Shrinking Free Space, Batman!


The hard drive in my recently built computer keeps filling up without explanation. I am running 64-bit Windows 7, an Intel Core i7-920, an MSI X58 PRO-E motherboard, 6GB of DDR3, and a Seagate Barracuda 7200.12 TB hard drive. I have 625.1GB free out of 931GB. When I came home a couple days ago, I found that I had only 17KB free on my hard drive. I restarted my computer to find that the levels of free space had returned to normal. I then locked my computer and went out for a meal. When I came back, I found I only had 234.7GB free. Every time I shut down the computer, the level of free space goes to normal, but then decreases rapidly whenever my computer is on.

I ran WinDirStat to try to figure out what the problem was; it showed that the largest chunk of used space—157GB!—was being used by a file called cputime.xml in C:\Program Files (x86)\Common Files\PC Tools\Monitor.

Joseph, this is a known issue with software from  PC Tools, such as Registry Monitor and Spyware Doctor, and has been fixed in the latest versions. Go to the Task Manager and end the SSDMonitor.exe and startmansvc.exe processes, then delete cputime.xml and logfile.etl from the “s? monitor” folder. Now, uninstall your PC Tools software and reinstall the latest version, and you should be all set.
