Hi
When you save files to your Mac, OneDrive or SharePoint, temporary files are automatically hidden by Mac OS or the cloud service.
When you save to other locations such as Box or a network drive, you will most likely see the temporary files while a document is open. These files store information about the referenced file name, but they are not your document.
This is normal behavior. When you successfully close a document, Word attempts to close all temporary files that are associated with that document.
You should not do anything with temporary files while the referenced document is open. Even just opening a temp file can result in corruption of the document.
