in the vault I need to move folders into folders

In the vault I want to move a complete folder into a new folder,

This is what I have done

I Take ownership of the folder (but it seems I can't take ownership, only of the files inside the folder)  but it does not says anything or it does not show any red circle that tells me that

I have ownership

Anyways I click change project and what it dows it changes the files, but not with the folder is there a way ?

let say: I have folders 1 to 500 that where created a while back then what I did I created a new folder with the name 1-50 so I can place all the folders  from 1 to 50 into that new folder but as I said only places the files inside

I need help, suggestions etc.

thanks
