I was about to agree with you and Ole but when I checked my 6.22 install disk I found that it had no hidden files. Maybe they go hidden upon installing them?
As we know, the IO.SYS and MSDOS.SYS files are usually marked HSR, but do not need to be that way. I note, like you, that the install disk does not mark them as hidden. I'm not going to try it, but suspect that they will be marked HSR upon installation. That makes me think that the diskette is perhaps damaged by a failed installation attempt. There should never be a hidden file with no bytes. I'm pretty sure that is the result of some mishap.
