Yes, once you’ve enabled iCloud drive in the app, then any chart file you import will end up in iCloud Drive, including any you get from email attachments. This is one of the wonderful advantages of Astro Gold’s ability to store chart files on the iCloud Drive. Also if you have Astro Gold for macOS you may find it even easier to import and store your Solar Fire chart files. On your Mac you just drag and drop chart files into the iCloud Drive Astro Gold folder (which appears as a new folder as soon as you enable iCloud Drive in any Astro Gold app).
