maybe I missed it but looked hard , is there a way for the file name numbering on the H to continue, rather than reset to zero once you delete any recordings or pictures ?
Someone suggested taking a pick before liftoff and one again after landing. Something to do with flight lengths but with flight logs that may be overkill.
Still make sense to take one just before power off and then keep that one after deleting any other files. The CG03 will continue on from that number
