I had to manually change the resulting ZORK2.ZAP which added new files (ZORK2_FREQ) without the extension, I have the impression if the file is named ZORK2_FREQ.zap it doesn’t need the extension, but if it’s ZORK2_FREQ.ZAP we need to include the extension name.

Note that ZILF 0.9 is out of date; newer versions shouldn’t have that problem.
