At the moment, Special:UnusedFiles produces a singular output showing images and either a file name (~25 characters) or partial file names (22 characters followed by an ellipsis), this output unmanipulable, and only apparently accessible via the Special: page.
This means that the files listed on the page can only be managed singularly for any maintenance
It would be useful to be able to generate a list providing full name, and not producing an image. I would see that this is an option that could be selected from the Special: page
