Record marked as obsolete and not updated for a long time.
Office SharePoint Designer was a specialized HTML editor and web design program from Microsoft. It was used to create and modify Microsoft SharePoint sites and web pages.
A .spdesignconfig file contains configuration settings for SharePoint Designer and forms part of the application's supporting files. The format is obsolete and is no longer generally used by current software.
Open a .spdesignconfig file with Office SharePoint Designer on Microsoft Windows. The program normally reads its configuration files automatically, so opening the file directly is rarely necessary.
The file stores application settings rather than user documents or SharePoint content, so it generally cannot be meaningfully converted to another file format.
