In Yuki, it is only possible to delete a folder from the bottom shelf in the Archive.
A deleted folder cannot be retrieved in the Archive

The documents are now moved to this folder.
To move only one document, open the document in question and click the Click here to store this document in another folder button.
Then, in the screen now opened, select the folder to which the document should be moved.
