Hi Adam
The pattern is most of all unclear.
I add a couple of tracks to the playlist.
Sync
Works fine
Then one day I do the same.
JRiver won’t recognize about half what is on the device so proposes to sync but of course run into overcapacity.
The only solution is to clear the file system of the phone and do everything from scratch
The petabytes are new to me, probably because I closed/opened JRiver a couple of times.
Looking at the file system of my phone, all files are in place
Phone is a Samsung GT-19100, Android 4.1.2
