I am very pleased the 64 bit version now works with Sony Walkman NWZ-E436F media player. However, I wish to report some bugs with MC24's management of files on the Walkman. The following relates to using the "Sony Walkman" device under the "Drives & Devices" section of the tree.
1) MC24(64bit) cannot delete playlists from the Walkman - even when the playlist is already empty. It is necessary to use Windows Explorer to delete any playlist from the Walkman.
2) A playlist modified on the computer cannot be over-written on the device - probably because the old file cannot be deleted. Playlists have to be deleted manually (using Widows Explorer) before a modified playlist (using the same name) can be successfully saved to the handheld device. Additional media files included on the new playlist are copied to the device during sync, but these do not appear on the Walkman's playlist - presumably because the Walkman's old playlist is not overwritten.
3) Audio files cannot be deleted from the Walkman by accessing the names via a playlist saved on the Walkman. However the filename will be removed from the playlist. A message says "Deleting" and the playlist is modified, however the file reported as deleted remains on the handheld. Refreshing the main "Details" list (updated from the handheld) indicates that the "deleted" files are still there. Fortunately, media files can be selected and successfully deleted via the main "Details" list, so this bug or is merely an occasional inconvenience.
MC24(64bit) should be able to provide a working interface to the simple file management operations mentioned above, but to date, deleting a playlist on this Walkman model (at least) does not work.
MC23(32bit) versions were performing satisfactorily, despite some inconvenience re-building the list of Playlists on the left panel (tree) whenever the whole list (of Playlists) disappeared from view after deleting a single playlist. This does not happen with the MC24(64bit) because it is not even possible to delete a playlist.
