Export files
You can export workflows to, and save or publish workflows from, Nintex Workflow 2013 export (.nwf) files. Export files are specialized XML files that persist both the SharePoint workflow and the Nintex-specific metadata needed to recreate a workflow in Nintex Workflow 2013.
Note: Nintex recommends that you do not manipulate the contents of an export file. Unpredictable results may occur. Use the ExportWorkflow service operation solely as a retrieval and persistence mechanism for workflows.
Exporting and importing workflows
You can export existing workflows either interactively, from the Workflow designer, or programmatically, from the Workflow web service, to export files. For more information about programmatically exporting workflows, see Exporting and importing workflows.
