Notes about the DHCD 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 DHCD file type is primarily associated with 'DHCD Computing' by DHCD Computing. DHCD files are used by specific application(s) designed by DHCD Computing to store program data or settings. These files are not designed for the user to manually edit them and doing so breaks the software license terms; however, they are generally stored in plain text format.
