Lost File Name

I am not sure if this is the right place to post this question but here it goes:
After burning files from the hard drive to a CD the orginal file name was shortened (i.e. hum12-2d.jpg became hum12~1.jpg). I wasn’t the person who burned the files but I have to figure out what the pictures are since the original file name refers to the structure photographed. Is there any way to recover the original file name?

Nope, if the names were changed you cannot change them back to their original name.
