Did you try opening the files in MSWord?

If MSWord opens it ok, I'd bet that someone opened it in MSWord and saved it
there (or had autosave turned on and that saved it).

If MSWord can't open it, then at least you've eliminated one more possibility.

When I opened these excel workbooks, it is not usable data to save in any
form. I am interested in knowing what has happened to my excel documents
that they won't open so I can stop it from occuring any more and also if
anyone knows how to recover these excel files.

I have Excel workbooks that I have been using over a period of years.
Recently, I have encountered a problem opening the workbooks and get the
message that "the file is an unrecognizable format". If I open it in text
mode, it is not usable data. Files that have been just fine will suddenly
have this problem. I have backups but once excel refuses to open the
document, I get the same message trying to open the backups. I have emailed
the files to another computer and it still won't open. So it appears that
something is corrupting the files. Any ideas?
