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

Data files categorized as DivX Descriptor 2 files are used by version 2 of the DivX Descriptor software, which was developed by Daren Softwares. These DivX Descriptor 2 files are saved in the DDCX format, a proprietary file format also created by Daren Softwares. These DDCX files are appended with the .ddcx extension and are primarily used for descriptive data entered and saved as DDCX files with the DivX Descriptor 2 program. The content of these DDCX files consists of details associated to digital video files encoded and saved in DivX formats. The DivX Descriptor 2 software can be used in Microsoft Windows-based systems to enter DivX movie-related details and save it in the DDCX format. The DivX movie-related data stored in these DDCX files may include the title of the DivX movie, names of artists and the director of the video and the duration of the DivX movie among other relevant pieces of information. The DivX Descriptor 2 software can also be used by Microsoft Windows users to edit the content of a DDCX file corresponding to a DivX movie file, for redistribution purposes. These DDCX files are similar to the DDC format, which is used by previous versions of the DivX Descriptor 2 software, except these DDCX files are encoded and integrated with XML-based specifications.

Launch a .ddcx 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 .ddcx 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 .ddcx files aren't yet associated with it. In this case, when you try to open a .ddcx file, you can tell Windows which application is the correct one for that file. From then on, opening a  .ddcx file will open the correct application.

Be careful not to rename the extension on .ddcx 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, .ddcx. 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.
