Hunting for files in explorer...

How do you currently organize files across multiple projects when they're scattered across OneDrive, network drives, and local folders? Or do you just… not?

Curious how other people handle this. I'm working on 3-4 projects at once (engineering consultant) and my files are everywhere, some PDFs in OneDrive, Excel sheets on my desktop, CAD files on a network drive. I spend way too much time just finding things.

Do you have a system that actually works? Or is everyone else also just navigating deep folder trees 10 times a day and pretending it's fine?
