I did my inital backups and things look quite fine. the only exception and problem I found:
when I login via ftp my folder with mp3-files looks fine. but when I use my favorite way of working (login via browser and map the drive) only a few of the mp3-files are listed, as well in windows-explorer as in the sync programs.
most of the mp3-files are lost (also, as I wrote, when connected via ftp, they are there)
Has anyone a hint, what the problem could be?
thanks for help
