I downloaded one of those practice multi tracks from After extracting zip it had 25 wav files each averaging 35 megs.3-4 where 75 mb's. Total of around 900 something megs. Saved project with copy files on USB 2.0 thumb drive. It took over 30 minutes to copy those wav files when I saved project.It took along ass time. Long enough for me to go take a shit and get something to drink and when I came back it was still copying files for another 5 minutes or so. Same sample rate. No converting.Files were 44.1/24 and project is 44.1/24. USB 2.0. Ive used same USB to transfer files that were gb's 1080p size files and files that were GB's of mp3's. They were no where as slow as this..
