In MB STUDIO, when you choose a file or folder, you may encounter the following message:
To load local files or folders use "This PC". Do not use network.
It means you are trying to load a local file or folder from the network
and instead you should use "This PC"
In fact, the network should only be used to access files or folders located on other computers.
Local files and folders must be selected by opening "This PC" and then the disk with letter for example C:\ or D:\ etc etc
