(Ya can't just rename the extension to EPUB.)
You might try and change ONE of those books extension to ZIP and see if it will open (as a folder) in windows. If so, you might be able to rename those books to ZIP and add those to Calibre

That won't work as they are not valid ZIP files. The worst case is the hard drive is failing and the data is getting corrupted.
The real question is, were these ever valid ePub in the first place?
