With MBOX, that is correct.
You can also just throw a separator at the end, like TOTO/ and it will 
create a folder that accepts subfolders.  Thunderbird is a little buggy 
in this area though with how it decides to treat them.
I submitted a patch last month to help with a bug Timo had found, but of 
course they haven't done anything about it.
