You're here because you have a file that has a file extension ending in .cl2. Files with the file extension .cl2 can only be launched by certain applications. It's possible that .cl2 files are data files rather than documents or media, which means they're not meant to be viewed at all.

Files stored in the CL2 format are specifically called HY-TEK meet results files. These files are affixed with the .cl2 extension and are generally classified as data files implemented with support for applications developed by HY-TEK Sports Software. A user of any of two applications from HY-TEK Sports Software can create, open and edit the content of a CL2 file, and these applications include the HY-TEK Sports Team Manager software and the HY-TEK Sports Personal Swim Manager program. These two applications can be installed by users of Microsoft Windows-based systems. Since these CL2 files contain meet results data of a project output file created using these applications, the content of these CL2 files is referenced by these applications when a user enters new content or makes modifications to its existing content using any of the associated features integrated into these programs. These applications were developed for scheduling and recording results of sporting activities, and details stored in a CL2 file may include participant data and competitor results. The HYV format was developed by HY-TEK Sports Software to replace the CL2 format. HYV files are implemented with better support for database storage and retrieval functionalities than CL2 files (which are compressed using plain text encoding specifications).

Launch a .cl2 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 .cl2 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 .cl2 files aren't yet associated with it. In this case, when you try to open a .cl2 file, you can tell Windows which application is the correct one for that file. From then on, opening a  .cl2 file will open the correct application.

Be careful not to rename the extension on .cl2 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, .cl2. 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.
