Hi.
I often use the projects of other authors. These projects have a lot of options.
for example in Project-> Build Settings...
To use them I change the file extension : progect.cywrk.autor_PCname ---> progect.cywrk.my_PC_name
Is there another more correct method?
You've stumbled upon the user file.
The user file should only contain things like open documents and window layout. It should never contain any build options. You can inspect it yourself as it is XML.
