Well, you can just do it from DOS:

   c:\> dir /s/b/a abc.txt

Just use os.walk() and check the list of files returned at each 
directory-level iteration.

   ROOT = "c:\\"
   fname = "abc.txt".lower()
   for p, d, f in os.walk(ROOT):
     for fn in f:
       if fn.lower() == fname:
         print os.path.join(p, f)
         # break

You might also investigate using os.path.normcase() instead of 
.lower()
