Does 3.0 use the same folders that 2.4.2 used?

2.4.2,each project had an associated folder for data.
Does 3.0.0 have the same?

I am not seeing them when I use 3.0.0, maybe they are being saved elsewhere.

In 3.x the entire project is held in a single database file. The file has a .aup3 extension.
