Updated Description In All MXD's in a folder/subfolders

Anonymous User

Original User: cdeaner66

New to Python here so please be patient.
I need to update the Map Document Properties Description field in hundreds of maps in one folder and multiple sub folders.

I figured out how to add a description to the current map by using the following:

import arcpy
mxd = arcpy.mapping.MapDocument ("CURRENT")
mxd.desc = "Description Text Here"

How do I modify this to loop through all the MXD's in my folder/subfolders to update this field in each map?

Any insight/help would be appreciated!

Thanks,
Chris

Let me know how this works for you:

import arcpy
import glob
import os

# Provide folder path to loop through (first level only)
folderPath = r"C:\TEMP\test"
for filename in glob.glob(os.path.join(folderPath, "*.mxd")):
    print "Editing", filename
    mxd = arcpy.mapping.MapDocument(filename)
    if not mxd.description:
        mxd.description = "Default description"
    mxd.save()
    del mxd

I found another script to do something similar to what I was looking to do and modified it for my needs.
It works (kind of), the only problem is I have 3 mxd's in the folder and it is only updating the last one.

Any suggestions?

Here is the code:

import arcpy, os
# Provide folder path to loop through (first level only)
folderPath = r"C:\TEMP\test"
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.description = "Python Test Description"
mxd.save()
del mxd

Thanks for the help Jason, it worked great!
Python is new to me and I appreciate the assistance.

The script worked for me as long as the 'description' field was empty.
Is there a way to overwrite an existing description for all MXD's in a folder?

Thanks
