Traceback (most recent call last):
  File "C:\Python27\Utilities\copyfiles.py", line 47, in <module>
    copyfiles(srcdir, dstdir)
  File "C:\Python27\Utilities\copyfiles.py", line 42, in copyfiles

I've noticed that the code runs if I use shutil.copyfiles instead of
shutil.copy. Do you know why?

I've also noticed that if I have a sub-directory, I receive a permission
error. However, if I use os.walk, then my code runs if I have a
sub-directory in my source directory. My problem then becomes that os.walk
doesn't actually move the directory, but instead just moves the files
within the sub-directory. Oddly, this code runs without permission error
when I use shutil.copy unlike the above piece which raises an error when I
use shutil.copy. However, if I use shutil.copyfile, I get the below error:
(Do you know why?)

Traceback (most recent call last):
  File "C:/Python27/Homework/oswalk.py", line 41, in <module>
    copyfiles(srcdir, dstdir)
  File "C:/Python27/Homework/oswalk.py", line 36, in copyfiles
    shutil.copyfile(srcfile, dstdir)
  File "C:\Python27\lib\shutil.py", line 82, in copyfile
    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: 'C:\\newtest'

The code where I use os.walk is here:

I am using Windows XP

I've checked the permissions on the folder and I have full control. I
haven't yet checked extended permissions and ACL's etc, but will do so.

Thanks!
