TryIng to clear some space on my MacBook and I noticed my Engine Prime Music Folder has made a copy of all the music I imported from my external hard drive. 56gb. Why did this happen? I was under the impression the music would just be analyzed from the external (like when I use it for Serato DJ) and then I would just copy it to my SD card. What happens if I delete this large file? Will it always duplicate all the music I import? I never keep music on my computers in case it crashes. Thanks for the help.
