Windows registry and system cleaner applications ?
My drive c is becoming very very low on disc space, and I need to reguarly delete and cleanup files both in the temporary folders in the User and Application Data.
Is there a free program out there that can find these cache folders and other old and unused folders so that I can get some free space on my drive c in windows 7?
CCleaner is a popular free "cleaner" app.
From the website
CCleaner is our system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware!
