File Attributes conversion

[Sam Collett]

I can get file attributes using os.path.getsize and os.path.getmtime
etc, but I am not sure how to convert them into something more
understandable

e.g.
File Size to display in bytes (if < 3kb), kilobytes (if < 2MB) and
megabytes (> 2MB). How would you do that (the value I get is 12345L -
what is the L?)

Modified/Created time to be displayed as GMT (DD mm YYYY, HH MM am/pm)
14/09/2002, 5:54pm (is it in seconds currently [starting from which
year]?)

I am doing this on Windows 98SE, is it possible to get the code to
work cross platform as well?

TIA
PS Can you also get other attributes (read-only, hidden, compressed,
system, archive, etc)?
