Hi. The transfer software does filtering as well as transfer. If you transfer files to the BP with Windows Explorer/the copy command/any other way, you will end up with unplayable text/html/word/whatever files, and will end up with mp3 files that you can play, but cannot navigate.

Can one directly copy a file from their hard drive to the BP drive, or does the transfer software do some file massaging in addition to the copying? In other words, is the BP transfer software a convenience or a necessity in the process of creating folders on the BP, copying and deleting files, renaming files, etc? Mike
