Thanks. That makes it a lot easier

Fairly certain that the win32file.CopyFile API call doesn't
handle wildcards. You have to do that yourself. (I could be wrong).

Quick check:
<dump>
Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os, sys
>>> import win32file
>>>
>>> os.chdir ("c:/temp")
>>> os.mkdir ("backup")
>>> win32file.CopyFile ("*.txt", "backup", 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
pywintypes.error: (123, 'CopyFile', 'The filename, directory name, or
volume label syntax is incorrect.')
>>>
>>> win32file.CopyFile ("temp.txt", "backup", 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
pywintypes.error: (2, 'CopyFile', 'The system cannot find the file
specified.')
>>>
>>> win32file.CopyFile ("exists.txt", "backup", 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
pywintypes.error: (5, 'CopyFile', 'Access is denied.')
>>> win32file.CopyFile ("exists.txt", "backup/exists.txt", 1)
>>>

</dump>

Sure enough:

1) Wildcards give the error you had
2) Non-existent file gives a suitable messag
3) Existing filename to folder name only gives Access denied
4) Existing filename to folder name + filename copies ok.

Now, that only took about a minute to run through on the interpreter
and check, so hopefully that'll help you out next time: create a
small test case (without all the long path names). Find out what
CopyFile can or can't do and act accordingly.

If you haven't already, look at the glob module:
