GetResource Description:

GetResource can scan the executable files (*.exe, *.dll and *.ocx) to extract the resource (Bitmaps, Icons, Cursors, Waves, Midi, AVIs). You can scan a single file, a directory include or not include the subdirectories, even all your disk.

It can skip the duplicate resource and works rapidly.

You can get thousands of resources at 20 minutes if you have enough files to extract.
