How to use Arma 3 mission structure checker?

An Arma 3 mission PBO must contain mission.sqm at its root and be named like MissionName.Map (e.g. co40_Escape.Altis). Paste your file list (one path per line): the tool flags the most common structure errors before packing.

  1. Enter the mission folder or PBO name (without .pbo), e.g. co40_Escape.Altis.

  2. Paste the file list (one relative path per line; e.g. from “dir /s /b” or “find . -type f”).

  3. Fix the errors (red) first, then the warnings (orange).

  4. Pack the folder with the PBO tool of your choice and put the .pbo in mpmissions.
