There may be some settings in the .pif file it uses. Pkzip is, IIRC, a 16-bit app, so it needs some of them. Now I don't know what .pif file - is it some fox.pif, or did Windows create a pkzip.pif, beats me.

Anyway, in the w9x days there were such settings in .pif files, where you could tell Windows how to emulate XMS (or EMS, if you prefer that) for your DOS app. Didn't need to touch that under NT4 or later, so I'll whistle the rest (*).

And btw, you may try to tweak the -) switch (yes it was a switch under PkZip :) - just type pkzip at the command prompt and RTFM that it will show you.

(*) from my high school slang - "dalje se zviždi" - one whistles further. Means you don't know the rest of the lyrics.
