Move Engine Prime Library to External Drive

Way easier really. You can upload your Engine Prime library to rekordcloud and then use Relocate Files to move them to a new drive. Then simply download your library and they will be at the right place. Of course Engine Prime support is in beta, so make a backup before doing this and let me know if it all goes well!
