This freeware program allows you to see into the big files in games like Quake 2 (go look in the BaseQ2 sub directory, see the big PAK0.PAK file, that´s one) and extract files to anywhere you want easily.

This version 5 is faster than any previous version, uses external drivers (DLL files) to read file formats and does not need those huge (2mb) DLL to run (like in version 4).
