Recovering Files After Microsoft Word 2016 for Mac Autosave Failure

I have Microsoft Word 2016 for Mac's autosave feature set to 1 minute. Word saves autorecovery files in an impossibly obscure location, so I in preferences I set the AutoRecovery files location to a sensible location.

Still, I had a crash and there were no Autorecovery files saved. Yet, I was able to eventually recover most of the work. I found these instructions after a lot of Google searching:

Mac OS creates temporary files located in your computer’s Temporary or TMP folder. The lost file may be located in this folder. To find this folder;

1. Launch Terminal (Applications > Utilities > Terminal)
2. Paste this command and press enter: open $TMPDIR
3. This will open tmp folder.
4. Open the folder named: “Temporaryitems”. Look for the Word folder and look for files with the approximate time of an Autosave prior to the crash.

Remove SXUPTP.kext from Mac

This file is not compatible with modern MacOS but it is hard to find it to remove. Here is the location

/Macintosh HD/System/Library/Extensions/SXUPTP.kext
