The CS10 automatically saves photos, videos, and Autolog videos to a job on the USB drive. The CS10 will open a new job if there is not already one on the USB drive. The CS10 will add a new session to an existing job if you use the same USB drive for multiple different jobs The CS10 will save media files to a new session to the job on the USB drive when it is ejected and when the CS10 shuts down. The CS10 will only record a new/separate job if you use a different USB drive for each job. You can split jobs with multiple sessions into separate jobs using SeeSnake HQ.
