what I usually do is like first letter (or two) for zone name, then one maybe two letters to describe what the contents are so, say I was making a .lvz for TW for replacements graphics, I'd call the .lvz something like "twg.lvz" for replacements bong sounds, I'd use something like "twb.lvz" "tws.lvz" for replacement sounds "twc.lvz" for replacement commands.hlp etc to remember which .lvz's I intended for optional download, I usually put a "+" in the name like "tws+.lvz" so I remember so it'll end up like misc:levelfiles=+tws+.lvz
