A file with .cf2 extension is a CAD file format that contains 3D package designs or other model data for die-cutting. Most of the CAD/CAM machines can process and cut these files. It was created by the National Space Science Data Center (NSSDC) to provide self-describing data storage and manipulation format that matches the structure of scientific data and applications such as statistical and numerical methods, visualization, and management.
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 CF2 into many other file formats. Please see the complete list below.
