Since changing file names in Calibre's library appears to be fraught with peril, would it - could it - be possible to change them from within Calibre, and have it update its db accordingly?

It may be that this is already possible, but if so I haven't found how to do it.

My reason for wanting to mess with file names at all is that I own a cheap but useful ereader, a MiGear, which ignores any title or author stored in metadata and just displays books in its library alphabetically, by file name.
