For my Windows 10 setup, AppData/roaming folder has a copy of the Objects folder, for MoI4beta, and also has a Commands folder with "non-standard extra scripts", mostly with a _ prefix. (_ prefix is not needed.)
The "standard" regular MoI4beta commands are in the C:\Program Files \MoI4beta... directory.

MoI3 files are under Program Files (x86), with their own copy of Objects folder and All commands.
