how to check which platform is active for the project? (from the project files)

i'd like to check which platform some project is set to, without opening unity.

so far have found these:
- Assembly-CSharp.csproj has some build target info, like StandaloneWindows64:19
- Library/PlayerDataCache/ most recent platform folder could be the one that is active
- not found in build settings anymore, https://answers.unity.com/questions...latform.html?childToView=317348#answer-317348
- ProjectSettings.asset does get touched if change platform, but its not changed.. (no platform info)
- Library/EditorUserBuildSettings.asset has few bytes (4 ints?) changed, but not sure..

are there some better ways?

 

You're on to something with \Library\EditorUserBuildSettings.asset - it is stored in here and can be accessed from within Unity environment as EditorUserBuildSettings.activeBuildTarget https://docs.unity3d.com/ScriptReference/EditorUserBuildSettings-activeBuildTarget.html, of course this isn't an ascii file...
