According to the help manual CM93 chart offsets are a binary file in the program data directory as CM93/... Can anyone be more specific on the file name. I have found several files like C_CM93_coverset_sigA. Is this the correct folder? I want to move all the chart offsets to a new computer.
When I made the same the files was stored in a CM93 folder in the same directory as your opencpn.log (Windows:C:\ProgramData\opencpn\cm93) and named like:
C__Path_to_your_charts___coverset_sigp.E and one similar for all A, B, C, D etc affected by your change.
