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.
Files with .XLT extension are template files created with Microsoft Excel which is a spreadsheet application which comes as part of Microsoft Office suite. Microsoft Office 97-2003 supported creating new XLT files as well as opening these. The latest version of Excel is still capable of opening these old format template files. Such a template file is used to quickly create new Excel files with default data and settings such as page formatting, font size, margins, charts, etc which can be further saved as new .XLS files.
You can also convert CDR into many other file formats. Please see the complete list below.
