ZXT/ZAX
From Just Solve the File Format Problem
ZXT/ZAX is a format for declaring extensions for ZZT worlds.
The file name extension is ZAX if it is a separate file from the world file, or is ZXT if it is concatenated the ZAX and ZZT file. (For example, cat TOWN.ZAX TOWN.ZZT > TOWN.ZXT is a valid way to make a ZXT file from a ZAX and ZZT file.)
