When you select a folder with bitmaps in Windows Explorer, it'll indicate all bitmap files using the same old icon. Did you know that you can make Windows display a thumbnail of those bitmaps instead?
- Run "Registry Editor" (run RegEdit.exe)
- Select "HKEY_CLASSES_ROOT\.bmp" and note the "default" value for it ("Paint.Picture" for example)
- Now select "HKEY_CLASSES_ROOT\Paint.Picture" ("Paint.Picture" being the default value as explained above)
- Double click on "default"
- Type "%1" without the quotes and press ENTER
- Restart Windows
Now when you view directories with bitmap files, you'll actually see a small (32x32 by default) representation of those pictures.
