Notes about the OKM 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 OKM file type is primarily associated with 'OkMap' by Gian Paolo Saliola. OkMap is a free software for many outdoor activities that might require a map. It can manipulate maps, trade data with mapping services, and more.
