Moving Audacity Files

I can not find out how to transfer audaity projects to another PC. So I save the project on a stick. What comes out is a folder with lots of subfolders, and when I plug this into the other machine, therre seems to be no way that audacity can read/open this. What am I doing wrong, or repectively should be doing?

Audacity’s “Project” format changed between Audacity 2.x and Audacity 3.x.

It sounds like your projects were made with an older 2.x (or even 1.x) version of Audacity.
Audacity 2.x is no longer supported (the current version is 3.1.3, and Audacity 3.2.0 is due to be released soon), but there’s some information about how to manage the projects in the old format:

Thanks a lot - I was using 2.3.2, wasnt even aware that its outdated. Looking forward to using the new one!
