Add network location to contentDir

[robgr]

I am running MinimServer on a QNAP TS212-P and have two entries for MinimServer property contentDir which are paths on the NAS, all is fine
I wnat to add a path on my networked PC which is \\STUDY\Users\robert\Music when viewed in Windows Explorer
If I copy this verbatim into contentDir for MinimServer properties I get the error 'Not an absolute path; correct highlighted value and retry'
Can I actually add a network path as described above?
If so then what is the correct nomencalture for the path?
I know I could run MinimServer on my PC but if the above can be achieved then it's just a single UPNP point for all my music
