As per the two attachments,one shows the path when on Android 5.2.0, and the other after the update to v. 6.0.1
Trying all,and by sheer luck I found the now cryptically named /storage/609A-F1FD/OPENCPN/ATLANTIC etc. is my extdrive.
Using my Solid Explorer File Manager,I can read/write to the Extdrive as before,and can see no mention of the /storage/609A-F1FD/OPENCPN/ path.
I also experienced that there is a limit to the amount of .kap charts
you can enter up in the path.
I normally have all my .kap charts
filed alphabetically in country order under the directory OCPNCPN but had to limit the number of kapīs by 4 areas. i.e. ATLANTIC,CARIBBEAN AND PACIFIC, (4 separate paths) as otherwise the app would crash.
To begin with,I think I uninstalled and re-installed 5 times,but later learned to reboot when the app crashed.
Even now,my Android OCPN will crash/hang now and again when I try to start it. Perhaps it depends on how much of the internal memory is available at startup time? Would it not be possible to load just the chart visible when you last used the app? and then open/close as you pan across the screen
Loading up ALL the charts in a limited memory seems a bit excessive??
I still have not found out how to insert/delete a waypoint in a route
This all has to do with Android 6.01
