Export result missing folders

i export all folders to an empty folder on an usb stick.
When i schroll the result i see the 2 most important local folders of my wlm are not on my stick.
I've also tried to export all the wlm folders except the imap account folders but again the 2 most important local folders are not on the stick
How can i export all my folders at once?

It's ok.i've found my folders n my export result.They were exported under a folder called with a special name "imported 21a"
