What is Windows disk Clean Up?

Disk Cleanup is a computer maintenance feature included in Microsoft Windows. It designed to free up disk space on a computer’s hard drive. There are a number of different file categories that Disk Cleanup targets when performing the initial disk analysis.

  • Compression of old files
  • Temporary Internet files
  • Temporary Windows files
  • Downloaded program files
  • Recycle Bin
  • Removal of unused applications or optional Windows components
  • Setup log files
  • Off-line files.

The above list is not exhaustive. For instance, ‘Temporary Remote Desktop files‘ and ‘Temporary Sync Files‘ may appear only under certain computer configurations, differences such as Windows Operating System and use of additional programs such as Remote Desktop. The option of removing hibernation data may not be ideal for some users as this may remove the hibernate option.
