trying to upload a Zm map

im trying to upload a map but i dont know how to make it in a zip file

Download and install WinRAR

Right-click the .bsp file of the map (and any other files you want to include, like custom content

Click “add to archive”

In the menu that pops up, make sure “zip” is selected on the left, not “rar”.

Click OK.

Windows can compress into a ZIP file without any extra programs, unless you’re on something older than XP.


  1. Built-in Zip compressor sucks
  2. WinRAR is great and massively useful

Right click the file, move to “move to” and select zip.
