What do you mean all of the filenames? All of the
filenames in a folder? All of they python files on
your computer? All of the files on your computer?

Yes, it is unportable. I just didn't download the
win32all extentions so that I wouldn't accidentally
write such unportable code. (If you need an IDE that's
better than Python but not the Win32 IDE, use the one
that comes with wxPython.) I would probably write the
code like this (but it wouldn't garbage collect
properly on Jython):

>>> infilepath = raw_input("input ")
>>> outfilepath = raw_input("output ")
>>> print >> file(outfilepath, 'w'),
file(infilepath).read()

There is probably a more efficient way to write it,
but I can't think of it. On my computer, it works
virtually instantaniously, so I don't really care if
it's as fast as with win32all.

Note: for most other cross-platform operations (that
would normally be platform-dependent), you would
usually use the os or sys modules.
