Notes about the HLN 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 HLN file type is primarily associated with 'MicroStation' by Bentley Systems, Incorporated. MicroStation is used by teams of architects, engineers, contractors and GIS professionals for work on buildings, civil engineering projects, power plants and geospatial information.
