Why are chart files calculated by Solar Fire 2 scrambled when opened in Solar Fire 3?
This is due to the fact that the upgrade from Solar Fire 2 to Solar Fire 3 underwent a change in chart file structure. In Solar Fire v2 start the Chart Import utility and select the chart file name to import. Then select for the destination directory the same directory C:\SOLFIRE\USERDATA. Then make sure that the destination filename is the same as the import file name. Then, under “File Type”, select the “Solar Fire” file type. Then click the Transfer button. This converts the original SF2 calculated chart file to an SF3 chart file type that Solar Fire 3 (and Solar Fire 4) can read.
