Minimserver not seeing one of my files

[NeilT]

As you know, I'm running Minimserver on a Rapbery Pi, and you've helped me with a couple of problems. This particular problem has me stumped so I'm asking for help.

I have a directory on the hard disc that stores my music, called Recordings and currently holding two live recordings (flac files) I made of a local group. Both have tags for Artist, Title, Album, and Track No. But only one is visible in BubblePnP. The one not displayed is a large file, some 45 minutes in length.

I have made the disc visible to the Sonos controller, and both files display correctly in that.

I am left now with the thought that it's something to do with the file size. Does anyone have an idea?
