I am glad you mentioned looking at the file in a hex editor. The one I provided didn't lend any info but I have serveral others that did. At the end of most of the files it says the file type is a PIXTIFF. Upon further researching I think it is actually a scanned file format.
Another update: The person actually found the program that opens them up but the problem is that I can only view 1 file at a time. So if I were to convert every file to pdf (there are 5,000 of them) then you can see how long it would take. Is anyone familiar with the PIXTIFF format? If I could convert them all in a batch program then I could eventually get them to .pdf format. Thank you again for all responses.
