The CDR file format is a vector image, possibly (picture or image), created with utility called CorelDRAW. The CDR file was developed by the well-known corporation Corel, so its application has spread exclusively to Corel's own software products.
CDR do not have the support of most special programs and image editors. In order to understand what a CDR file format is and how to work with it, you should know a list of certain utilities. The most popular of them are Corel DRAW Graphics Suite X7 or Corel WordPerfect Office. The program allows you to export the CDR file to more common other formats.
Company Corel took care of working with files in CDR format in a graphical editor of its own production. There are several official utilities that allow you to open a CDR without changing the original file extension; the most common one is the Paint Shop from Corel Corporation. For better compatibility it is recommended for that vector images enclosed in a CDR file format to be saved via the Graphics Suite program in the CorelDRAW CDR format (version 9.0 and earlier). If the CDR file is implemented in the tenth version, then you can successfully open it using a software product "Adobe Illustrator".
The CDR file often contains a bitmap image or one or another element of vector graphics, which is also a drawing. The CDR extension can be converted to more free and accessible formats for mass applications, for example, the SVG file format.
