Hi Dave,
This is an interesting but tricky question! My reason for stating this is that the JB7 music format is different to the BB1 music format and I haven't found a direct method of converting from one format to the other.
The JB7 stores the music data in a single level folder format of 'Artistname Albumname' with the album tracks stored in this folder. The only way to get this data out of the JB7 in bulk is to plug a USB device into the JB7 and run the 'USB Menu' --> 'Backup Music'.
This will give you your music collection on the USB device in a diectory '\hardfi\music'
However each folder is in the format of 'Artistname Albumname'. (with 3 spaces between the Artistname and the Albumname).
For the BB1 to display artists and album names absolutely correctly, each single level format folder above needs to be converted to a two level folder format of 'Artistname\Albumname' with the music tracks stored in the 'Albumname' folder.
This is where some possibilities arise.
1. You can directly 'Import' the JB7 'Backup' into the BB1. However, the main 'Artists' screen will only display a single artist named 'Music' instead of the individual artists. You can click on the 'Music' artist and the list of artists will be displayed along with the album names.
2. If you have a B2, you could use the JB7 Backup and plug the USB device into the B2. Then use the B2's 'Main' --> 'USB Menu' --> 'JB7 Functions' --> 'Restore USB C' function. This will restore and convert the music folders and files to the correct format for a B2 or BB1. Once the 'Restore' is complete, the you would run the B2's 'Export to C' function which will export the music folders to the USB device.
Then you would transfer the USB device to the BB1 and run the 'USB Functions' --> 'Browse USB A' --> <Select folder>' --> 'Press Next to Import' and your music will be loaded in the correct format.
3. If you don't have a B2, then you should consider a 'file format conversion' program. These can be found on the Internet. I ran a test today of my JB7 Backup files converted using 'dBpoweramp' (mainly because I use it for other conversions) which is more for converting 'flac' files to 'mp3'. You specify the source file (your JB7 Backup) and then you specify the target file and dBpoweramp copies the folders into your target folder in the correct format. 'dBpoweramp is free to use for 21 days and then is about £30 for a permanent licence.
4. This option will depend on the size of your collection. If your collection is relatively small, you could plug the JB7 USB Backup into your PC/Mac and manually do the conversion to the BB1 format. For each JB7 music folder, create a new folder named 'Artistname' then drag and drop the relevant folder for that 'Artistname' into the new folder. Then rename the 'Artistname Albumname' to 'Albumname'.

Peter.
