Mime Typeapplication/octet-stream


CDT is a native file format used by CorelDRAW created in 1989. It is a vector graphics format that started life on Windows 2 and has evolved over the years to support newer features and is still as popular as ever.

These files are binary in format and usually represent a group of assets in a zip format (whilst retaining the CDT file extension). CorelDRAW is still being developed today and is the primary program for working with CDT files.
