I am trying to select particular files within

You might find glob a better starting point:

ActivePython 2.6.6.15 (ActiveState Software Inc.) based on

Python 2.6.6 (r266:84292, Aug 24 2010, 16:01:11) [MSC v.1500 32 bit(Intel)] on win32

Type "help", "copyright", "credits" or "license" for more information.
>>> import glob
>>> help(glob.glob)
Help on function glob in module glob:

glob(pathname)
    Return a list of paths matching a pathname pattern.

    The pattern may contain simple shell-style wildcards a la fnmatch.

>>> for filename in glob.glob(r'C:\WSG\GL\2011-08\*.txt'):
    print filename

I have been able to do both but not together!
When I try to select my files within the dir loop nothing comes up, but
when I leave the files outside the dir loops it selects all the files
not just the ones in the dirs I have selected.
The code I am using is:

import os

MainFolder=r"D:/samples/"

for (path, dirs, files) in os.walk(MainFolder):
     for dir in dirs:
         if dir=='01':
             print "selected directories are:",dir

             for ncfile in dir:
                   if ncfile[-3:]=='.nc':
                         print "ncfiles are:", ncfile

Any feedback will be greatly appreciated!!
