Thanks for your assistance. I now have the RPI2 running with OPENCpn including the plugin for the chartdldr.
My have a background working with DOS, and such there were files that we would make copies of and store within the program so that if something got corrupted we could rename the file back to the original and usually correct the problem. I am just learning
how UNIX works so my question is along those lines, are there files that are good to make a copy of, if so what are they.
Also is there a way to copy the working image and store it?
I had one odd issue this A.M. Last night I logged off OPCENCPN and shut down my system. This morning when I turned it back up, none of the charts
were listed in the OPTION -- CHART FILES Directory. They were still in the OPENCPN file I made for them, so I had to reload them. Anyone know why they disappeared and how to keep this from happening again?
Thanks for the assistance with answering my questions.
