I gave that some thought but I doubt that it would work because I have almost a gig of stuff on my hard drive backup and I only have a 128 meg SD card. If the files were changed to KN7000 format as a part of the restore, much space would be saved because of the file compression. But I doubt that that is the case so I don't think I'll try because I have almost finished the transfer doing it manually. And you only have to do it once.
What I would really like to see is some of the utilities that were included with the Tech Manager added to the Song Manager. Since the KN7000 does not support long file names it is not possible to see the string name that the user has entered unless the file is being viewed at the KN7000 SD display (or with an editor that most users wouldn't use). The Tech Manager provided for a computer print out of the hard disk content that showed the string name associated with each file. That cross reference was invaluable to me in the process of weeding out and moving the KN5000 files to the SD card. The file management system for the SD card looks almost exactly the same as the system used by Key Soft Service for their hard drives with the exception of the 16 character string as opposed to the 20 character one. So most of the software code could be used for the Song Manager. The Song Manager is very basic to say the least.
