The SPDESIGNWFDOCLIB file extension is related to Office SharePoint Designer, a specialized HTML editor and web design program used to create and modify Microsoft SharePoint sites and web pages.
Office SharePoint Designer is Microsoft's Windows application for creating and modifying SharePoint sites, pages, and workflows. The SPDESIGNWFDOCLIB extension identifies data used by the application's workflow document library features.
This is a specialized file associated with SharePoint Designer and SharePoint site content. It is intended to be handled by Office SharePoint Designer rather than edited as ordinary text or HTML.
Open the file on Windows with Office SharePoint Designer, the Microsoft application associated with the format. Because the file is used by SharePoint Designer's workflow document library features, it may need to be accessed from the relevant SharePoint site rather than treated as a standalone document.
A general text editor or web-design program is unlikely to display the file correctly.
This application-specific workflow data is not intended for conversion to a common document format.
To preserve or reuse its content, open it in Office SharePoint Designer and use the application's available SharePoint publishing or export features. The available options depend on the associated SharePoint site and workflow.
