Notes about the BTY 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 BTY file type is primarily associated with 'Railroad Tycoon 3' by PopTop Software Inc.. Railroad Tycoon 3 lets players experience railroading from the Golden Era through to the modern day. The game challenges players to create and expand their own railroad empire.
