@reolink-lorenz Why? This makes no sense, if I want to delete all my video files at once there should be a way. If I can delete 1 page at a time then the option should be there to do multiple pages or days at a time. You make it sound as if we do not know they will be gone forever, I have an issue once full and it says it will delete the files in a loop it misses some recording that should have happened when full, it does not delete correctly or fast enough once full to capture some recordings. Depending on the sub makes the issue even more frustrating. It would seem this is done so a person would want/have to upgrade. As a programmer I know it is possible it should be available to all, I have DVR's I can use but for time's sake I bought a sub if the option does not become available soon I will cancel my sub and add my cameras to my network DVR.
