A .CFL file can contain several different types of data depending on the software that created it. The most common use is an interactive lesson file created by Promethean ClassFlow. Teachers use this software to build and share digital classroom lessons.
Common CFL Formats
Another frequent format is a flowchart or diagram file generated by the older CorelFLOW software. In the gaming and 3D avatar industry, a .CFL file might be an IMVU Product File used by the IMVU platform to manage virtual items, or an FMOD compressed sound bank. Scientific engineers may also encounter .CFL files as CFD General Notation System files.
How to Open CFL Files
To open these files on your computer, you need the original software. You can use ClassFlow for interactive lesson files, or compatible Corel programs for diagrams. If you do not have the specific software, you can use standard archive tools like 7-Zip or the `unzip` command-line tool to inspect the contents of the lesson files, since they use standard compression.
Identify and View Online
Because a .CFL file has multiple possible meanings, you need to know exactly what kind of data is inside before you can work with it. viewer.online/cfl analyzes .CFL files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because .CFL files use the known ZIP format, viewer.online/cfl can safely open and display them online, eliminating compatibility problems.
