Sometimes vey long paths by export project archive

Does anyone know why i have sometimes very long paths by exporting a project archiv?

It copys the source file system. Is that a bug or can i change this anywhere.
It's only sometimes.

My project as a multicam timeline, 2 mp4s and 1 mp3.

It copys the source file system.

That's why.

I don't believe we have any control of that directly, other than using a different folder structure on the hard drive, of course.

IIRC, you can ignore the file structure when doing Media Management. But it has its own traps…
