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

ObjectDock files are saved in the DOCKZIP format and can be created and used with the ObjectDock software. These DOCKZIP files are affixed with the .dockzip extension and are generally classified as data files, since the content of these DOCKZIP files mainly consists of data associated to program and application settings, icon images and background graphics entered by the author of a DOCKZIP file during the creation of the .dockzip project output file. A DOCKZIP file can also contain folders with files entered by the author of the DOCKZIP file using the ObjectDock software, since this program was developed by Stardock to provide users with a set of features that can be used to create "docks" in a Microsoft Windows platform. These "docks" are similar to the "docks" also found in Mac platforms, and this means users of computers running on Microsoft Windows-based systems can install the ObjectDock software to implement support for the creation and modification of these DOCKZIP files to improve the visual appearance and navigability of their Microsoft Windows desktops. Animated mouseover functionalities can also be implemented into these DOCKZIP files, and these files are encoded using compressed archive format specifications.

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

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