The pwdef file extension is associated with ArcGIS, a geographic information system developed by Esri for Microsoft Windows. ArcGIS allows users to work with maps and geographic information.
The pwdef file contains project information used by ArcGIS. It belongs to the ArcGIS project rather than representing a general-purpose map or geographic data format.
Open a pwdef file with ArcGIS on Microsoft Windows, or open it from within ArcGIS.
A pwdef file is an ArcGIS project file and is not normally converted directly to another file format. Open it in ArcGIS and use the software's export tools to export any maps or geographic data contained in the project.
