Hi @Joshua Lebreton ,
Do you want to xcopy the file structure in the SharePoint server library to another server? We need to map to the network drive first, and then xcopy. The file server on Microsoft's server is in another domain, right? If it is not a server in the same domain, I suggest you look for a third-party tool to see if this function can be realized.
About map SharePoint as a network drive, please refer to: https://learn.microsoft.com/en-us/answers/questions/614462/linking-sharepoint-site-to-a-network-drive
