If you do save it, it is still possible to recover a temporary file.

1, open a word document, and there is a file option in the upper left corner. Click it.

There is a vacancy here. After clicking, there is an option at the bottom. Can be restored.

Finally, when editing a word document, you must remember to save it at any time, and use the shortcut key Ctrl+s, which is very convenient, habit-forming, simple and cool, and you don't have to worry about unexpected situations such as sudden power failure. Of course, word is becoming more and more perfect now, and there is an automatic saving function every once in a while. Personally, I think it's a good function. You can set it up.
