problem with os.system calls under win32

Actually I was trying a similar thing, and decided to be smart and use
os.path.join
but this is what happened:

>>> import os
>>> os.system(os.path.join("D:","My Documents","test.bat"))
'D:\My' is not recognized as an internal or external command,
operable program or batch file.
1

However:
>>> os.path.exists(os.path.join("D:","My Documents","test.bat"))
1

That's a bit confusing !

Of course from Gordon's example:
>>> os.system('"%s"' % (os.path.join("D:","My Documents","test.bat")))
0

works

Regards,
Paul
