Consider the following scenario:
- On a SharePoint Online site, you have a Promoted Links list.
- In the Promoted Links list, you create a link to a local file that uses the file:// protocol.
This is the expected behavior in SharePoint Online. This issue occurs because the file:// protocol isn’t supported for local files in the Promoted Links list. The http:// and https:// protocols are supported in the Promoted Links list in SharePoint Online.
