You're here because you have a file that has a file extension ending in .dhcd. Files with the file extension .dhcd can only be launched by certain applications. It's possible that .dhcd files are data files rather than documents or media, which means they're not meant to be viewed at all.

DHCD Computing Application data files are stored in the DHCD format, and these files are appended with the .dhcd extension and integrated into the File Sniffer software. DHCD Computing developed the File Sniffer application as an implemented service into DHCD Computing applications. The File Sniffer program can verify the legitimacy of software copies from DHCD Computing. User settings and application configurations of specific DHCD Computing programs are stored in these DHCD files. When the software needs to validate the legitimacy of a DHCD Computing application copy, it references the data stored in these DHCD files, matches the associated data with the corresponding details and confirms the authenticity of the DHCD Computing application copy. These pieces of data stored in a DHCD file are integrated with encryption and encoding specifications proprietary to DHCD Computing and can only be viewed through the settings page of DHCD Computing applications. Users of Microsoft Windows-based systems are advised to not open or tamper with the content of these DHCD files, because modifications done by a user to a DHCD file may cause the DHCD Computing application to crash or fail to initialize.

Launch a .dhcd file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .dhcd file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .dhcd files aren't yet associated with it. In this case, when you try to open a .dhcd file, you can tell Windows which application is the correct one for that file. From then on, opening a  .dhcd file will open the correct application.

Be careful not to rename the extension on .dhcd files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .dhcd. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
