Here’s a quick tip for anyone using Windows Vista. When using Windows Explorer (My Computer), you’ll notice that green glow that slides across the location bar when browsing a directory. It is building thumbnails of all files in that particular directory – movie files have a screen capture as the thumbnail. As you can imagine it slows down file operations considerably. To turn this feature off (and speed up your computer), Open up Explorer.exe, go to Tools -> Folder Options -> View. Then go to the Advanced Settings and check “Always show icons, never thumbnails.”
By default, Explorer does not show the file menu, so press ALT-F to show the menu while in the window.
