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

Kingsoft Presentation files are project output files generally classified as data files and stored in the DPS format. These DPS files can be created, opened or viewed and modified using the Kingsoft Presentation software, an application integrated with features for authoring and publishing digital slideshow presentations, similar to the functionalities implemented into the Microsoft PowerPoint software. The content of a DPS file is usually a series of slides embedded with text, images and other multimedia objects like audio clips, sound and visual effects. Users of the Kingsoft Presentation software can enter text formatting attributes and other slide layout elements in a DPS project. Microsoft Windows users can install the Kingsoft Presentation software to start creating, opening and editing the content of these DPS slideshow documents. Android users can on the other hand install the Kingsoft Office suite of applications where Kingsoft Presentation is bundled as one of the programs included in this software suite. The Kingsoft Presentation software is also implemented with support for the conversion of PPT files into DPS slideshow documents.

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

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