So, how exactly do you make an uncompressed zip folder? I made a working BMZ once by right clicking and selecting "send to > compressed (zipped) folder" but that's never worked again. Thelonesoldier 07:20, 29 October 2010 (UTC)
- You'll need a more advanced tool such as WinRAR. 7-zip may also suffice although I have never tested it. --Omnicoder 18:50, 29 October 2010 (UTC)
