I use two computers. That is the great thing about dongles. When I back up a song to bring to my other computer, some wavs are missing. This is because it does not make sense for me to store my audio files of samples I make for Groove Agent in the pool. Why not? Because my samples are for use in multiple songs. I have a central place to store them and to back them up. I don’t want to go digging around in song pools to load my samples into Groove Agent. I should be able to back up with all samples used to one folder and while we are at it, an option for a single file back up. I assume when switching computers, most people use the back up option.
