Available disk space decreases every time a game is run

The amount of available disk space on my machine decreases every time I run a game - what should I do?


Disabling System Restore for any drive which you do not back up regularly is not recommended.


There are several causes for this condition which this article will not cover:

  • Game patches and updates are being downloaded automatically through Steam
  • Files for saved games are being created (for single-player games)
  • Custom content downloads are occurring (for multiplayer games)

If you notice that 50 - 100 MB of available hard disk space is being used every time you start a game, you may need to disable System Restore for the drive which is storing your game files.

For more information, please see the Microsoft Knowledgebase article for the System Restore feature.
