.ZBLORB File Extension

Z-machine game file used by Interactive Fiction (IF) interpreters such as Zoom and Spatterlight; contains the story contents in a Blorb wrapper which enables inclusion of other gameplay files, such as .AIFF files for sound effects and .MOD files for music.

ZBLORB files are similar to .BLORB files but are compatible with only Z-machines. They are the same as .ZLB files. BLORB files containing Glulx games will most likely appear with the ".gblorb" or .GLB extensions.
