May I add a collection from other NAS

[sky176]

Dear Simon
My setup is like this:
Qnap (with miniserver) (I don't always turn on my computer, so I install miniserver in QNAP instead)
NAS (Melco N1A, where my songs are)
Destop Windows 7 (miniwatch)

May I install a miniserver on N1A?
If not, how do I add Melco music folders onto the miniserver, which sits inside the QNAP?

Best Regards,
Sky Ma
