All is wrong!
0. Wrong import
1. not "E:\myDir1\MyDir2", but "E:\\myDir1\\MyDir2"
2. dir and files are in the SAME directory. In other words if the
structure is:
myDir1
    MyDir2
       somefile.py
the first itteration will give an EMPTY dir= [] and files =
['somefile.py']


Here is an example from the manual:

This example displays the number of bytes taken by non-directory files
in each directory under the starting directory, except that it doesn't
look under any CVS subdirectory

import os
from os.path import join, getsize
for root, dirs, files in os.walk('python/Lib/email'):
    print root, "consumes",
    print sum([getsize(join(root, name)) for name in files]),
    print "bytes in", len(files), "non-directory files"
    if 'CVS' in dirs:
        dirs.remove('CVS')  # don't visit CVS directories

so if you want just print full path of the files in E:\myDir1\MyDir2

for root,dir,files in os.walk("E:\myDir1\MyDir2"):
    for j in files:
        fille = os.path.join(root,j)
        print fille

Do not touch dir. It is supposed to be used to restrict the search.
If you do not modify dir it walk will progress into root's
subdirectories.
