Notes about the D4C 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 D4C file type is primarily associated with 'Dataphor' by Database Consulting Group LLC. Dataphor is an open source application development platform designed to streamline the process of designing, developing, and maintaining software applications.
