If Everything isn't finding something in particular, something you *know* is there because you saw it in a folder with your own eyes, and you didn't make a typo in the search field, then delete Everything's database and restart the program.

Whichever version of Everything you have, the file is going to be named "everything.db". It'll be rebuilt when the program is restarted.

Stupidly embarrassingly enough, Everything itself couldn't/wouldn't find this particular file for me. You may have to dig it up in Explorer. Beyond that, life should be good
