Jim, I always keep
ENC and RNC in separate folders. Some people don't.
I generally use RNC with the Android version, but I did have RNC and did not keep it up to date and ended up removing that folder because I needed more room on the
cell phone.
If you have folders under "Charts" IE Charts/ENC and Charts/RNC and you download each Coast Guard Region using Chartdownloader, make sure each region is pointing to an new
destination subdirectory such as "Charts/RNC/GC-01" or "Charts/RNC/CG-05" and Charts/RNC/CG-07"
Then you can Add Chart pathnames to the Charts Tab, pointing to each CG region.
IE Charts/RNC/CG-07
Then in the Chart Group TAB I always make an "Empty" group after "All charts" and then make a CG05 group for example and then add the path to the group...Add path "Charts/RNC/CG-05". Now you will be able to right-click on the chart area and select "Chart Groups" and then pick "GC05" . Your android will be much faster than sorting through "ALL Charts" and you have quick access to each Chart Group all the way up and down the
east coast.
Hope this is clear and answers your question.
1. I would not put them in the same directory.
2. I would keep RNC and ENC in separate directories.
3. I would have each Coast Guard Region in a separate subdirectory under RNC or ENC depending on which type of chart.
4. In Charts Tab I would add separate paths for each Coast Guard Region.
5. Then I would set up separate Chart Groups for each Coast Guard Region so I have quick access to any of them from the
screen.
