Folder doesn't appear after rescan

[alexj700]

I own a Synology DS412+ with MinimServer installed since a long time (years). Actually running MinimServer 0.8.5.3 update 133.

My problem is that when rescanning, one folder called "Antonio Vivaldi - Federico Guglielmo - Le Quattro Stagioni - SACD" is never recognized by MinimServer and it never appears on the music list in my Linn Akurate DS/3 streamer.

If I look for it by folders at the streamer using my NAS instead of MinimServer, I can see it and the music is played, by using Minimserver as always, this folder doesnt't exist.

I can say that the music files have long names and long tags, and all of them are *.dsf files, only if that could help to find the problem.

Many thanks in advance....
