You should set your workspace up to map to a directory at or above the project's directory

Getting 'You should set your workspace up to map to a directory at or above the project’s directory.
', and wondering why. Am I not allowed to have workspace on a different drive on same machine ?

Using Perforce as Source Control | Unreal Engine Documentation , says nothing about having to use another machine , something I heard on forums, maybe bad advice.
Anyway the docs perforce are horrid and very outfdated, or I’d not be having these problems, very antithetical to progress :wink:

I watched tuts on youtube but useless.
What now ?

TY~! ;))
