Does nautilus warn before starting copy/move of files into ext4 partition which is too small?

As a user with non root privileges, when copy/moving a bounch of folders and files, in one batch, from some device into another different partition which is ext4 and too small (space allocated to user) to contain the entire batch of files and folders, but big enough to contain say half of them, and also big enough to contain all of them when considering the special space allocated to root, does nautilus warn before starting or does it interrupt the copy/move when filling the space available to the normal user? The copy/move is done through the GUI with right mouse click -> copy/move and then right mouse click -> paste.
