error sending path to Win OS

[Earl Eiland]

A couple of you commented that I should be using os.path.join. 
Accordingly, I rewrote my code.  Unfortunately, I still have the same
problem.  the following code snippet

Results.SetOriginal(os.path.getsize(os.path.join(InputDirectory , x)))
y = str(x.split('.')[0]) + '.rk'
print InputDirectory, y
raw_input()
Results.SetArchive(os.path.getsize(os.path.join(InputDirectory, y)))

is executed from the command line with
C:\Documents and Settings\eeiland\Desktop> ..\Thesis\Plan2\Compressor.py
Test_Data\ Test_Output\Results
Test_Data\ Book1.rk, where InputDirectory (in the above snippet) =
'Test_Data\' (I've also tried 'Test_Data', with the same results).

x (in the above snippet) is an element of the list generated by
os.listdir(InputDirectory).

Output upon execution is as follows: 
Test_Data\ Book1.rk

Traceback (most recent call last):
  File "C:\Documents and Settings\eeiland\Thesis\Plan2\Compressor.py",
line 60,
in ?
    Results.SetArchive(os.path.getsize(os.path.join(InputDirectory, y)))
  File "C:\Python24\lib\ntpath.py", line 229, in getsize
    return os.stat(filename).st_size
OSError: [Errno 2] No such file or directory: 'Test_Data\\Book1.rk'

What am I doing wrong?
