Right on such files os.stat() crashes with "OSError: [errno 22]

how can such files exist? and how to create such files
programmatically for a test?
what is the underlying cause for the crash?
Can you give us a specific example? Some Windows viruses install a file
system filter to render some files inaccessible, and it's possible to
set file permissions so that you don't have the right to look at that
kind of information.
Didn't think of that; I assumed that the underlying FILETIME was
sufficiently corrupt as to preclude a valid date/time being
generated from it. Explorer fails gracefully and displays a blank;
the API call fails and is reported as an exception by Python.
I was going to try to generate such a "corrupt" number but haven't
had a chance yet.
