Because of hard drive spaces issues, I've set up two Scheduled Tasks in Control Panel:

  1. To run CCleaner
  2. To run a batch file to shut down the system, erase unnecessary files and reboot.

The log showed an exit code of 0 for each task, yet the low available hd space listed looks as if nothing had been deleted. When I manually run these programs, everything works fine. What's the problem?

The computer is a Compaq Presario 5400US, 256 RAM, Windows XP Prof, Windows firewall, AVG anti-virus, 5(!) GB HD, Internet Explorer 6, AOL 9, broadband Internet. We received the system as a refurbished gift (original specs were Windows XP Home, 20 GB HD). Buying a new system isn't in the picture right now, so your help is appreciated.
