A DWT file is an AutoCAD drawing template file that is used as a starter for creating drawings that can be saved as DWG files. Such template files provide initial settings such as unit types, the precision required, title blocks, layer names, line types, and other similar information for lateral conversion to proper drawing files. Both AutoCAD and CoreCAD can be used to read the template files and utilize them further.
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 DWT into many other file formats. Please see the complete list below.
