To upgrade your music and move the music from your mobile caddy to your dj system
you need to do this from windows from your desktop click on my computer click on the E drive or D (this is the mobile caddy)
then click on MP3 MUSIC* one time (highlight) go to edit click on copy.
then back to my computer click on C drive go to MP3 MUSIC click paste
the computer will ask do you want to overwrite these files yes no all click on all
it will take about 35 to 45 minutes to do this.
*do the same with the record case usely in a folder called diddj or cliff bell or tom or something like that

if you want to you can do the above in reverse from your djsystem to you mobile caddy
