What is a .MS-ONE-STUB file?
The file extension .MS-ONE-STUB refers to a Microsoft OneNote Stub file. This type of file acts as a shortcut to quickly access a Microsoft OneNote notebook that is saved on Microsoft OneDrive, which is a cloud storage service. Essentially, an MS-ONE-STUB file doesn't contain the notebook itself but rather a link or reference to where the notebook is located on OneDrive.
These shortcut files are automatically generated when you use Microsoft OneDrive or Microsoft OneDrive for Business to store your OneNote notebooks. This makes it easier for users to open their notebooks directly from OneDrive without having to navigate through the storage folders manually.
To open an MS-ONE-STUB file, you will need to use Microsoft OneDrive. You can access OneDrive on a computer through the web by visiting the OneDrive website, or by using the OneDrive application installed on your computer. When you click on an MS-ONE-STUB file, it will direct you to the OneNote notebook stored online in your OneDrive account.
