I think I have a problem related to the previous posters' issues.
I was able to find the option discussed here to copy files by directory structure rather than tags, which I want. Here is my issue.
I am trying to copy from my music library, J:\Special Drive\Music Library, to Device\Storage Media\Music. In the device and library settings, the appropriate folder paths are named. But I only want to copy the CONTENTS (files/subfolders, etc.) of the music library folder...instead, my device winds up with a path of: Device\Storage Media\Music\Music Library. Is there any way I can prevent this?
