Turn Off Thumbnail Caching

Every time you go into a folder which contains either pictures or movies, Windows creates a thumbnail image so you can see what that picture/movie is. The thumbnail cache helps speed up access to the thumbnails instead of having them load up every time you go into a folder, but each picture you have in a folder will take up around 2kb's. Follow these steps to disable this:

 1. Go to 'Start->Settings->Control Panel'
 2. Double-click on the 'Folder Options' icon
 3. Click on the'View' tab
 4. Check the 'Do Not Cache Thumbnails' checkbox
 5. Click Apply, then click OK
