This, and also:
1- 7zip is really easy to use with .ap files. In Windows Explorer, right-click on a .ap file, choose "7-zip", "Open archive" and there you are, looking at the files inside. To extract a file or folder, just drag it where you want.
2- You can also make 7-zip the default program for opening .ap files, so that a simple double-click will open them.
3- Use RW-Tools for extracting .ap files.
