Notes about the IGC file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The IGC file type is primarily associated with 'Global Positioning System' by Fédération Aéronautique Internationale. "IGC" comes from "the International Gliding Comission". IGC-files provide a standard for exchanging data logs from GPS flight recorders. For example, in competitions, a pilot shall submit an IGC file to the organizer as a proof that s/he has completed the competition task. The IGC file format is a text format that can be read by text editors.
