Notes about the RLF 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 RLF file type is primarily associated with 'ArtCAM' by Delcam plc. ArtCAM is a program for 3D modelling and CNC machining, which allows you to create high quality products from 2D artwork.
