SharePoint has an optional feature that allows documents within SharePoint to be accessed using a document ID address, in addition to the usual URL (http://) address. When this feature is enabled, SharePoint automatically translates any references to the document ID address to the actual URL of the file. It is therefore possible for links in documents in SharePoint to contain link paths that address the child file by its document ID instead of its actual URL.

LinkFixer Advanced has the optional ability to automatically translate and store link paths by document ID instead of by URL address. You can access and control this feature from the “Options | Web Access” screen, as shown below.

Choose “Use Document ID” only if you are certain that Document ID Service is enabled on your SharePoint site, and only if you are certain that you want to store all links using their document ID instead of the full URL address of the child file.
