"After extraction, you should have 144 main folders, 922 sub folders, and 20,869 files."
A fellow cruiser here in the Philippines
gave me such an extract (CM93ed2 MAY 2009) along with an OpenCPM which doesn't seem to work (I probably need to download it directly) although on his laptop
they worked together just fine.
All I really want is the files that cover the Philippines
so I picked off the 02700360.A and tried to view it in NavPak Pro (which I purchased four years ago but have never used) to see if I understand the naming convention. NavPak Pro says it uses C-Map
but it doesn't like the ".A" file extension - so can I rename the file to the correct file extension or is this too easy.
Can I just extract the files I want (the instructions imply that this can be done as it recommends putting charts
into geographical areas)?
