Using mapped drives to NAS server on Windows 10

I’ve been having trouble with this like crazy too, I had to drag and drop files in all last season, so I figured I’d try to nail it down this season. I have a Kodi box with a mounted USB drive that is shared \kodiname\My Passport\Recordings
I get this error which I think has to do with the share name, most likely the space in My Passport not being supported?
ERROR : The given path’s format is not supported.

If the space is the problem, I’m not sure how to rename a shared mounted USB drive in Kodi, but at least that’d be a start.

I’ve tried mapping the drive first, then pointing the monitor to R:, but I get
ERROR : Could not find a part of the path ‘R:\’.

I know it has to be one little mistake somewhere, but I’ve been racking my brain for months.

Thanks
