POPython copy files to a new directory and rename if file name already exists

copied!<p>I've already read <a href="https://stackoverflow.com/questions/10036489/copy-a-file-to-a-new-location-and-increment-filename-python">this thread</a> but when I implement it into my code it only works for a few iterations. </p> <p>I'm using python to iterate through a directory (lets call it move directory) to copy mainly pdf files (matching a unique ID) to another directory (base directory) to the matching folder (with the corresponding unique ID). I started using <code>shutil.copy</code> but if there are duplicates it overwrites the existing file. </p> <p>I'd like to be able to search the corresponding folder to see if the file already exists, and iteratively name it if more than one occurs. </p> <p>e.g.</p> <ul> <li>copy file 1234.pdf to folder in base directory 1234.</li> <li>if 1234.pdf exists to name it 1234_1.pdf,</li> <li>if another pdf is copied as 1234.pdf then it would be 1234_2.pdf.</li> </ul> <p>Here is my code:</p> <pre><code>import arcpy import os import re import sys import traceback import collections import shutil movdir = r"C:\Scans" basedir = r"C:\Links" try: #Walk through all files in the directory that contains the files to copy for root, dirs, files in os.walk(movdir): for filename in files: #find the name location and name of files path = os.path.join(root, filename) print path #file name and extension ARN, extension = os.path.splitext(filename) print ARN #Location of the corresponding folder in the new directory link = os.path.join(basedir,ARN) # if the folder already exists in new directory if os.path.exists(link): #this is the file location in the new directory file = os.path.join(basedir, ARN, ARN) linkfn = os.path.join(basedir, ARN, filename) if os.path.exists(linkfn): i = 0 #if this file already exists in the folder print "Path exists already" while os.path.exists(file + "_" + str(i) + extension): i+=1 print "Already 2x exists..." print "Renaming" shutil.copy(path, file + "_" + str(i) + extension) else: shutil.copy(path, link) print ARN + " " + "Copied" else: print ARN + " " + "Not Found" </code></pre>
