GED (and their predecessor, GMP) files are Game
Maker Extension Packages
(version 1.02) without the actual dll/lib/scripts/etc data, which is
stored separately in a DAT file. They are created by the Extension
Maker. Related is the
GEX (where DAT is also documented), which is an
installable extension, essentially combining the GED and DAT files into
one file.
The Extension Maker version 1.01 was made for GM 7 beta, and it used GMP
files (with a .gmp extension), which, as far as I'm aware, use exactly
the same format). When GM 7 was fully released (as in, no longer beta),
the Extension Maker was bumped up to 1.02, and GMP was replaced by GED.
For notes on how to read this format, and other information, please see
Format info.
