Switch Off The Thumbs.db Image Cache File in Windows

Thumbs.db is an image cache which makes thumbnail viewing faster. The file is automatically created in Windows Vista, 7 and 8 whenever images are encountered in a folder. It’s usually hidden but can appear, disappear and is often impossible to delete.
Fortunately, there’s an easy way to prevent further Thumbs.db hassle:
  • Ensure you’re logged in using an administrator account.
  • Hit Win+R, type gpedit.msc in the Run window and click OK. The Local Group Policy Editor will be launched.
  • Navigate through the tree to User Configuration > Administrative Templates > Windows Components > then either Windows Explorer (Windows Vista/7) or File Explorer (Windows 8).


  • In the right-hand pane, double-click “Turn off the caching of thumbnails in hidden thumbs.db files”.
  • Select Enabled (don’t make my mistake of choosing “Disabled” — you’re enabling the switching off of Thumbs.db. Not particularly intuitive, Microsoft!)


OK your way out and it’s job done — you’ll never be troubled by Thumbs.db files ever again!
