Multiple Xojo apps using the same Libs-folder

I remember that it should be possible to deploy each file only once, e.g. not deploying a *Libs folder for each helper app your MainApp may be using.
Just cannot find it anymore. Who knows how to do this. I have the main exe and the helper exe in the same applicationfolder.

From what I remember you just need to rename de *Libs and *Resources folders to just Libs and Resources. Or is it just for *Libs?

You must also make sure that all of the apps are compiled with the same version of Xojo, in case that’s not obvious.
