After you open a Word file, there is a hidden word on the desktop

Why do I have a hidden Word file on my desktop after I open a Word file
This hidden document is the Word document that you are opening and editing.
Because Word has the automatic save feature, the purpose is to restore the document when it is reopened after a sudden crash (such as a power outage).
As long as you quit the document you are editing (either saved or not saved), the hidden document disappears.
If you do not run the Word program and appear this hidden document, the basic description of the last time you quit a Word document, the system thinks you are not the right to exit (such as the panic after the forced exit), this document is the resulting temporary backup document. If you do not need to, you can delete it directly.
