Re: Randomise files in directory?

If you have Python installed (www.python.org), the following script will do
what you need. You just need to insert your directory name where indicated.
I used five characters because this script will fail if the filname already
exists under windows. It should be safe for several thousand files. Make
sure you have a backup, I have tested this a few times but you are
responsible for your own data. BACKUP! Save the script as "renamer.py" and
run the command "python renamer.py" from the directory where you saved it.
Post back if you have questions.

-----begin script-----
import os
import random

mypath= 'c:/temp/test/' ##insert the path to your files
##between the quotes
##using forward slashes
##don't forget last slash
def randomName():
a = random.randint(97, 122)
b = random.randint(97, 122)
c = random.randint(97, 122)
d = random.randint(97, 122)
newname = chr(a) + chr(b) + chr(c) + chr(d) + '.jpg'
return newname

for files in os.listdir(mypath):
os.rename(os.path.join(mypath, files),
os.path.join(mypath, randomName()))
-----end script-----
