Playing Music from my NAS

I am New to roon - Might sound stupid - I have added my NAS folder in the setup screen successfully - How do i then access & play the files. In Sonos - there was a folders access , where i could access the NAS storage - where do i do it in Roon

Albums and tracks should just just appear in Roon. Did you check if there is anything new under Artists or Albums? Does Roon show you the number of tracks in found on that share (under Storage Settings)?

Yes it is showing me +1000 tracks . Since i imported my iTunes also . The albums & tracks are populated. But i dont see any flac files in the album & tracks which is what i stored in my NAS
