BACK UP FILES

[harkeychad]

Well I really messed up yesterday. I ended up saving a file from 2019 to 2020 and I did not mean to do that. I am trying to find the back up files so I can get it back. Can anyone lead me in the right direction please?

Well, you might be able to find an older version in your where you're local files were if it was a workshared modeled.
If it's not workshared, you might be out of luck, unless you have a nightly backup.
When you opened the model in 2020, you should have gotten that big warning dialog box that says something like "You're about to upgrade to a 2020 version"
You can't really go back and I don't know that any of the back up files are going to be helpful.
Might want to contact Autodesk Direct about that one. I was told a while ago that while Autodesk says you can't go backwards, apparently you can, it'll just cost you a small fortune.

At revit everything is bad with backups. If it is a local file - look for files: .0001.rvt .0002.rvt, etc. (but it rarely helps :()
