If the offset = 0xFFFFFFFF, then the field FILE DATA contains the attributes of the file size, name and extension (type). Transfer of each new file starts at offset 0xFFFFFFFF Packet!B42

If the offset! = 0xFFFFFFFF, the FILE DATA field contains data to be written to the file at offset obtained in this variable Packet!B43

All packages FILE, belonging to the same file have the same time of the formation (unixtime) Packet!B44
