Notes about the CT2 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 CT2 file type is primarily associated with 'CTRAN/W' by Geo-Slope International. CTRAN/W is a finite element software product that can be used to model the movement of contaminants through porous materials such as soil and rock.
