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

A user word list file is integrated with a set of data encoding specifications proprietary to Corel, and these specifications are implemented to allow the storage of data saved in a user word list file in the UWL format. The content of a user word list file includes a list of words and phrases entered by a user of a supported application with a grammar and spell checker applet. The grammar and spell checker applets of these programs locate the associated user word list file to reference the data stored in the file in order to provide the user with access to the grammar and spell checking functionalities integrated into these supported programs. These applications need to locate the associate user word list file because there can be multiple UWL files, each one intended for a particular language. The Corel WordPerfect software is an example of an application that uses these user word list files for its grammar and spell checking functionalities. The Novell GroupWise program is a word processor application implemented with support for using these UWL files, and this program has versions developed for Microsoft Windows-based systems, Linux and Mac platforms. These user word list files are appended with the .uwl extension.

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

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