Notes about the MYC 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 MYC file type is primarily associated with 'Simply Safe' by Joshua Cannon Butcher. Simply Safe Backup has been written as a replacement for other Windows backup products including the one that comes with Windows. This file type was used by versions 2004 and earlier.
