Notes about the MYT 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 MYT file type is primarily associated with 'MyTraffic X' by BK & simMarket.com. MyTraffic X works with Microsoft Flight Simulator X. By design, it is built to support all the new features FSX has to offer, like jetways docking to the AI aircrafts or luggage carts and other ground vehicles servicing them.
