Why a file starting with ~$ is created when openin

问题:

We all might have noticed the creation of a file named "~$filename.docx"(hidden) when opening filename.docx using MS Word

What is the purpose of this file?

Why is it created and what does it contain?

回答1:

It maintains temporary information about the current state of the document.

Have you ever encountered a crash and when you open Word it asks you to recover certain documents that were being edited? That's where it gets that information.
