Why does the brave 7 shooting a video generate multiple files?

For Brave 7,due to design, all videos will not exceed 7 minutes in length.You need to format the SD card in the camera before using it.
If loop recording is turned on, you can select 3 Min/5 Min/7 Min, Loop recording allows your camera to overwrite old files with new files. Once the memory card becomes full, the camera will delete the first video file to make room for the latest file. For example, if the setting for loop recording is “1 Minute”, then the camera will create video clips of 1 minute in length, and a 1-minute clip will be deleted when the camera needs more memory.
If you turn off loop recording, the camera will record 7 minutes of video footage until the card is full.
