Set the starting folder
Use a starting folder to show a department or project branch immediately, instead of opening the whole library.
- Edit the page and open Settings → Source.
- Select the site and Document library first.
- In Starting folder (server-relative path), enter the existing server-relative path, for example
/sites/hr/Shared Documents/Policies. - Enter spaces,
%and#literally. Do not paste a full URL or pre-encode the path. - Save or republish the page and verify that the intended folder opens.
Choose the navigation boundary
Enable Restrict navigation to the starting folder to make the starting folder the top of the visible branch. The tree, breadcrumbs and folder links cannot navigate above it inside this web part. When this setting is off, the starting folder still opens first, but the library root is available for navigation. An empty starting-folder setting uses the library root.
❗ Important
The navigation boundary is not a security boundary. Users retain their SharePoint permissions. Open in library opens the full library interface; disable that action if you do not want to offer this route from the web part.
Check an invalid location
The starting folder must belong to the selected library. If the folder has been renamed, deleted or made inaccessible, correct its path or permissions. A deep link outside the allowed branch does not override the configured navigation root.
