Not able to find Project Files.

The learning modules are in UE version 4, I am in 5.4. Is there a way to access the Project Files? I am having a difficult time.

If you are talking about assets, in 5.4 (compared to 4.x) just press ctrl+space or if you want to add content browser window just press Window > Content Browser → Content browser 1

If you are talking about project files as in explorer the easiest way to acces them is to press right click on any folder and “Show in Explorer”
