.WDN is AutoCAD Electrical project-related data

The wdn file extension is mainly related to one of the project-relate files from AutoCAD Electrical. 

The wdn file is a text file used specifically for auditing. In this file, terminal numbers are not checked for duplication. You can use wildcards to exclude a range of terminals for duplication checking such as all terminals with a tag name starting with "T" and with terminal number "1." AutoCAD Electrical searches for the <project_name>.wdn file in the same folder as the project definition file (.wdp). If <project_name>.wdn is not found, AutoCAD Electrical looks for the DEFAULT.WDN file in the project folder:

Windows XP:
C:\Documents and Settings\{username}\My Documents\Acade {version}\AeData\Proj

Windows 7, 8, 10:
C:\Users\{username}\Documents\Acade {version}\AeData\Proj

The default .wdn file contains the terminal number filers GND, PE, and E. They are ignored when checking for duplication and are not listed in the Electrical Audit report.
