This doesn't answer your question directly, but it might help you as
supplementary info:

You can see the file names for your (file-visiting) buffers in at least these
ways:

1. Menu-bar menu `Buffers'.

2. The buffer-menu buffer, `*Buffer List*'. You access this using command
`buffer-menu' or `list-buffers', typically bound to `C-x C-b'.

HTH.
