| Description | CorelDraw is a vector graphics editor developed and marketed by Corel Corporation of Ottawa, Canada. CorelDraw file formats include CDR, CorelDraw Compressed (CDX), CorelDraw Template (CDT) and Corel Presentation Exchange (CMX). | The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc. |
| Technical details | The CDR file is a ZIP-compressed directory of several files, among them XML-files and the RIFF-structured riffdata.cdr with the familiar version signature in versions X4 (CDREvrsn) and X5 (CDRFvrsn), and a root.dat with Corel Draw X6, where the bytes 9 to 15 look slightly different. | Office Open XML documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files, along with a specification of the relationships between them. Depending on the type of the document, the packages have different internal directory structures and names. |
