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

A universal binary JSON file is integrated with data interchange formatting specifications that were developed by The Buzz Media, and these universal binary JSON files are implemented with digital data compilation and storage standards used to generate data files and save them in the UBJ format. Affixed with the .ubj extension, these universal binary JSON files were developed by The Buzz Media to implement support for storing data in its binary format instead of its native text format, with its binary format being a representation of its text format. The creation of a universal binary JSON file requires the integration of the UBJ (Universal Binary JSON) format into the content stored in these universal binary JSON files. The UBJ file format allows the pieces of data saved in a universal binary JSON file to be shared in a more portable format because of the size of these universal binary JSON files. The UBJ file format was developed to promote universal cross-compatibility support for these universal binary JSON files and many programming languages. Quick data parsing functionalities are also integrated into files appended with the .ubj extension.

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

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