What is .AN file extension?
When saving a project in Edge Animate, you actually save an .HTML file. After choosing to save, Edge Animate creates a folder containing the .HTML file. However, it also creates the AN project file and associated .CSS and .JS files required for the animation.
AN files can be used to create .ANTMPL template files:
Select File → Save As Template..., name your file, select the save location, and click Save.
NOTE: Adobe Edge, the predecessor to Edge Animate, uses the .EDGE extension. This extension can be used interchangeably with the ".an" extension. However, the ".an" extension is now the default.
