I have searched for this issue but I think that I am using the wrong words for it. I am actually trying to set folder types in Windows Explorer to Music so my Zune software will find the folders. If I go to the customize tab of the folder properties window I can select the proper type and apply it, but once I leave properties, the types reverts to general documents, My files are either .wma or .wmv plus album art. All of that usually work in WMP. Can anyone please help.
