Qunpack is designed to take the fragments of the Quake game (V1.01 to V1.06) off its CDROM (or where ever it is held) and extract the contents into a standard Acorn directory.
This is to allow the PAK files and other Quake text files to be read easily without having to use a PC card to decompress them first!
When you run Qunpack it will take the fragments and extract automatically the contents of the full Quake game or if you've only got the Shareware fragments it will extract these too!
Qunpack may be downloaded (V1.03) from here - QUNPACK (94K Zip file)
