Background

• The Disk Cleanup utility is supplied with Windows and scans your hard disk for any temporary files that are no longer required. This utility can recover hard disk space and speed up your computer.
  
  

Operation

• When you run the utility, it checks your hard disk drive for various temporary files such as Internet cache files. It also offers you the option to compress files that are rarely used, allowing you to free up more hard drive space.
  
  The scanning process takes a long time, which can cause users to think the program has stalled. If you wait several minutes, the utility will continue.
  
  

Maintenance

• The Disk Cleanup utility, along with the supplied Disk Defragmenter utility, forms a useful maintenance regime for your operating system. It will keep your PC working well if it is used with regular antivirus and spyware scans.
