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?
