Python -?- FindAndReplaceWorkspacePaths for directory and all subdirectories?

[JeffPickles]

I'm looking to update a bunch of file references in MXDs througout a directory and all included subdirectories. This is a project I've been delaying until the ArcPy module was available, but now that it's here I'm having an issue getting it to work with those pesky subdirectories.

In the ArcGIS 10.0 help file, there is this topic regarding the Python FindAndReplaceWorkspacePath function.

I'm looking to tweak this code (example 2 from that referenced link)...

import arcpy, os
folderPath = r"C:\Project"
for filename in os.listdir(folderPath):
    fullpath = os.path.join(folderPath, filename)
    if os.path.isfile(fullpath):
        basename, extension = os.path.splitext(fullpath)
        if extension.lower() == ".mxd":
            mxd = arcpy.mapping.MapDocument(fullpath)
            mxd.findAndReplaceWorkspacePaths(r"C:\Project\Data", r"\\ComputerName\Project\Data")
            mxd.save()
del mxd

This code only seems to work for C:\Project and does not touch any MXDs in subdirectories.

How can I tweak this to include subdirectories in the process?

Hi Jeff,

I use the os.walk function to do any recursive directory "thingies" ...

Here a stub-code sample you might find useful:

# -*- coding: utf-8 -*-
# ---------------------------------------------------------------------------
# ListMXDs.py
# 
# Usage: ListMXDs <Directory to search>
# ---------------------------------------------------------------------------
import sys, os
#path to search - here hardcoded
theDirectory=r'C:\Archive'
#if parsed as argument
#theDirectory = sys.argv[1]
#File-Pattern to search
thePattern = "mxd"
#cycle through the directory and find all Files of type ...
for root, folders, AllFiles in os.walk(theDirectory):
    print "********** \nWorking on folder "+root+"\n**********"
    # now find mxds and print their names        
    for oneFile in AllFiles:
        #only do something if it is an mxd
        if oneFile.endswith(thePattern):
            print oneFile
