Certain tracks not available

[ahl032]

Hi there. I am a new user of MinimServer and have become so to escape the gravitational pull of iTunes. On my Mac I am using Swinsian and on my Android devices I am using BubbleUPnP. I have noticed that, since I have moved my music library on my Mac, that only some tracks within an album, all of which I know to be there in Swinsian, for example, and are certainly visible within the Finder, are not visible on BubbleUPnP. Being new to this, I am wondering what I should be looking for to solve this problem -- for example, inadmissable characters or spaces in the file name, permissions, etc? Is it a MinimServer problem or something to do with BubbleUPnP? Typically, I use FLAC files but generally the library has an assortment of file formats.

My apologies if this is rather basic, but thank you in advance for any pointers.
