An EDX file is a diagram created by Edraw Max, a professional diagram application. It contains a diagram, which includes charting shapes, arrows, and text. EDX files were replaced by .EDDX files, which are also used for storing diagrams but are smaller in size.

Some template categories include Engineering, Floor Plans, Maps, Software, Web Diagram, and Network. Under each of these categories, you're able to choose the specific template you want to use. To create an EDX file you must first open a template you'd like to use. You can do this by opening Edraw Max, then under the New tab on the left you can choose from the "Template Categories," then choose one of the "Templates." After you open your template, go to File → Save As.... After opening the Edraw Max program you can actually open up different EDX files and they will be displayed as tabs in the program. NOTE: The compressed version of this file is the .EDXZ extension.
