Help with Linux Mint 21.3 Installation

[ebeachlr]

I have accomplished the tasks laid out for me and the server is now running. However, the paths to the media files from the previous installation have disappeared and the new installation will not allow me to access them. I get a message back saying "The path could not be found. Please ensure the path is valid and try again." The path is reachable with Krusader and in the terminal app. I am sure that the problem is with my not understanding how to determing the proper path in Linux, but any help would be appreciated.
