No need to lie.
Like anyone has those unknowns memorized... Go get Zezula's listfiles
and add them using the instructions from the stickied tutorial:
Get "Starcraft-Brood War.txt" from this .zip and save it in your WinMPQ folder. Now, open WinMPQ, select 'Options...' from the menu, then go to the 'File Lists' tab and 'Add Listfile...'. Now select "Starcraft-Brood War.txt", which you just downloaded. Now open an MPQ and you'll find the ~unknown files are now gone, and there are useful names instead.
