A CDR file is a vector drawing image file that is natively created with CorelDRAW for storing digital images encoded and compressed. Such a drawing file contains text, lines, shapes, images, colors, and effects for vector representation of image contents. It can be used for the representation of various graphics data like brochures, tabloids, envelopes, and postcards. Besides CorelDRAW, other Corel products such as Corel Paintshop Pro and CorelDRAW Graphics suite can also open the CDR file formats.
Docx is well-known format for Microsoft Word documents. Introduced from 2007 with the release of Microsoft Office 2007, the structure of this new Document format was changed from plain binary to a combination of XML and binary files. Docx files can be opened with Word 2007 and lateral versions but not with the earlier versions of MS Word which support DOC file extensions.
