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 PPTM extension are Macro-enabled Presentation files that are created with Microsoft PowerPoint 2007 or higher versions. They are similar to PPTX files with the difference that the lateral can't execute macros though they can contain macros. PPTM files can be edited by opening them in Microsoft PowerPoint and updating the contents. Another similar format is PPSM but it is read-only by default and starts the slideshow when opened. PPTM, like PPTX, contains slides for different presentation elements like text, images, videos, graphs and other related material.
You can also convert CDR into many other file formats. Please see the complete list below.
