Notes about the LMK 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 LMK file type is primarily associated with 'Sprint-Layout' by ABACOM Ingenieurbüro. Sprint-Layout is a tool to create layouts for single-sided and double-sided PCBs (Printed Circuit Boards).
