Where do my imported contents go?

Development Asset Creation

I just converted a scene into Unreal, so have all the files in my project.
How can I save it, that i can use it for other projects?

It seems that when I start a new project, those files are not there.

Can I only use it for the current project?

Thank you

Thank you, I will put them all in a folder, and copy them whenever needed.
