Much appreciated!
I thought I tried every combination, guess I didn't try this as it

Hi group, I have a text file that contains thousands of lines and each line is 256 characters long.

Chris,
Much thanks. That's just what I need.
Jeff,
Not sure what's taking up the "available" space, but it's about 12GB

moving multiple directories
Hi, I need to organize thousands of directories full of files. I want to move these directories into other subdirectories. For example, all the directories that start with 01, move to a directory named "one", all directories that start with 02, move to a directory name "two", and so on I can't seem to find any easy way to do this. Looks like shutil.move only lets you move if the subdirectory DOES NOT exist, so after the first directory moves, the script blows up on the second move. I guess you could use shutil.copy or shutil.copytree but then you have to delete as well. Much longer process when you have hundreds of gigabytes of data. Thanks for your help!

Re: os.chdir doesn't accept variables sometimes
A simple way to get all the files throughout the directory sturcture...
You may have to rewrite the "CONVERTING" part.
import os, glob
for root, dirs, files in os.walk(os.getcwd()):
for file in files:
if file.endswith(".mp3"):
print "File: " + os.path.abspath(os.path.join(root, file))
print "CONVERTING "+file+" to
"+file[:file.index(".")]+".mp3"
file = file[:file.index(".")]+".mp3"

I think I've tried everything now and can't figure out how to do it.
I want to read in a text list from the current directory,

My text file would look something like this:

It seems like something like the following
code should work, but it doesn't.
