IconChanger can change the icon of a separate file regardless of its type. The project has been abandoned and can only be used as shareware. The evaluation version of IconChanger can change no more than three icons and is limited to finding a maximum of 3000 icons.

If you have hundreds of mp3 or doc files, you can change the icons of your favorite files to emphasize them. Right-click on a file whose icon you want to change and select Change Icon. The explorer-like interface helps you to find and select an icon for the file or for all files of the same type. You can drag favorite icons to a list and have easy access to them later.
