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. It is still as popular as ever.

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