Error: couldn't open file

[Michael Leuty]

Sorry if this is a well-known problem, but I can't find any reference to it in the archives.

I'm running MinimServer 2 on Synology DSM 7. A small number of albums that are available from the Synology server do not appear on MinimServer [Synology]. When I look at the MinimServer log file, these albums appear there, each file prefixed by "Error: couldn't open file", e.g.
Error: couldn't open file Beethoven, Ludwig van/Symphonies [Rattle; Berlin Phil] {192}/Symphony No 1_ I Adagio molto - Allegro con brio.flac

I've tried re-indexing the media files on my Synology and then rescanning in MinimServer, but the problem persists.

Can anyone help?
