Mapped drives

Since migrating to a Windows 10 computer I keep getting an error message when trying to do a file transfer from a local mapped network drive.

I know that seems like a bit of an oxy-**bleep** but if I remotely browse to a Windows 7 computer that has the same mapped network drive -OR- I attempt to connect to any othercomputer using the Windows 7 computer that has that mapped network drive, I do not get this error. See description and error below.

'Navigation to folder not possible "F:\": The system cannot find the file specified (Error: 2)'

Is this strictly a Windows 10 problem or is it a permissions error? Does anyone else have this issue?
