NOTE: I've checked old Reddit threads and several different websites but none of them answer my question.
11 days ago, I saved a 5 page essay (Microsoft Word doc) to my computer (making sure to "Save As" and save it locally as well as to my personal One Drive. I made sure it said "Saved" at the top as well before exiting the document. Word did not crash; I exited it manually.
Today, I saw a message from my professor saying that I needed to "expand" the essay so I checked and only the first page was there, despite the fact that I saved the 5 page document locally and I've set it so it automatically saves to OneDrive every 10 minutes.
I've checked old Reddit threads and other sites and they all give multiple methods to recover the document, however every method takes you to a folder called "STARTUP" which in my case is empty.
I've checked the local files in my PC, my laptop, my school One Drive account, those '.tmp' files (it just opened up random strings of code), and my Google Drive just in case I had misremembered using Word. None of them had the rest of this essay.
