Is there an option to capture the PTP structure in the `--get-all-files` function?

PTP is directory based and usually reflects the layout of the card with
a /store_xxxxxxx/ identifier in front.

gphoto2 -L

will show it.

And yes, if you shoot more than 10000 files in one go on a DCIM layout
you will need to change from a generic "gphoto2 -P" to a per-directory
download script I would say, or perhaps use the --filename option with
some datestamp in it.
