I have approximately 1500 raster files following this format:


I need these subsetted to, for example: 3609922nw. What are appropriate methods to rename large numbers of spatial data, that may or may not contain ancillary files (e.g. .xml, .ovr)?

Does it have to be ArcPy? If the filenames are that uniform, it is easy to create a batch file that does what you want using a combination of Excel and a text editor. Otherwise, with moderate difficulty (no more that ArcPy) you could write a batch file that uses regex to rename the files. – user3461 Jun 13 '12 at 19:31

Something like this ought to get you going...

import os
import arcpy
from arcpy import env

# directory containing rasters to be renamed
RASTER_DIR = 'C:/MyRasters/'

env.workspace = RASTER_DIR
for raster in arcpy.ListRasters():

    # get the raster name and file extension
    fileName,fileExtension = os.path.splitext(raster)

    # do some shenanigans to rename the file
    # based on your sample raster name, fileNameParts would look like
    # fileNameParts[0] = m
    # fileNameParts[1] = 3609922
    # fileNameParts[2] = nw
    # fileNameParts[3] = 14
    # fileNameParts[4] = 1
    # fileNameParts[5] = 20100425

    fileNameParts = fileName.split('_')
    compactFileName = fileNameParts[1] + fileNameParts[2] + fileExtension
