Easy CD Creator
From Just Solve the File Format Problem
In 1996 Adaptec purchased Corel CD Creator and it was combined with Easy-CD Pro to form Easy CD Creator[1]. CD Creator software allowed the user to create a Data or Audio CD layout by adding files or music in order to burn a disc. This layout could be saved for later use. The layout only referenced the file location and not the files themselves. It appears most versions were not backwards compatible with the saved "layout" file[2].
File Identification
CL2-CL4 files are based on the Microsoft Compound File format[3].
