NW-E00x Mp3 File Manager was meant to replace the Sony Mp3 File manager. The project grew and became JSymphonic a reviewed version with more features. This program is no longer maintained, please visit: https://sourceforge.net/projects/symphonic/
nwe00xmp3man works perfectly, thanks
Thanks for existing , since I have a NW-E95 That is Gen 1 or 2, and not supported by Jsymph... but I have no clue about how to copy MP3 files from Player to PC, at least not in the version I have 1.1.
