Notes about the CYL 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 CYL file type is primarily associated with 'Ribbons'. Molecular graphics software. Use ms-cyl command in Ribbons to convert .DOT to .CYL.
