CDX File - opening and understanding

Did your computer fail to open a CDX file? We explain what they are used for and recommend software that we know can open or otherwise handle your .CDX files.

What is a CDX file?

A .CDX file is a CorelDRAW Compressed file. Files that contain the .cdx file extension are most commonly associated with the CorelDRAW graphics editing application. CDX files are compressed CDR drawing files. When the CorelDRAW application is used to create a computer drawing, the file is saved in the CDR file format.

When the CDR file is compressed, it is given the .cdx file extension. This makes it easier for users to email CorelDRAW image files and transmit them via the Web.
