I would need a clarification of an iTunes feature "Add folder to Library" (without automatic copying of media files to the default iTunes folder). I know this adds all media files from the selected ("external") folder to the Library, and uploads them to iPad upon sync. However, does this also mean that any changes to the folder that was added this way, will result in subsequent changes to the Library (and, in turn, iPad) as well? E.g. if you add or delete a song to/from such ("external") folder (within Windows 7 file system), will such change also result in automatic removal/addition of the songs from/to the library (and, in turn, iPad)? Or is "Add folder to Library" a one-time activity only? One more thing... is there some sort of (over)view where you can see which ("external") folders have been added to the Library?
