Hey,,
So far I have this: @ECHO OFF setLocal EnableDelayedExpansion
set str=abcdefghijklmnopqrstuvwxyz set /a a=0 set /a max=25 :reset set ran=%random% set /a ran-=1 if %ran% gtr %max% goto reset if %ran% lss 1 goto reset set st=!str:~%ran%,3! echo %st%
set cnt= set ran=
it gets a set of 3 random characters from "str" well, kinda random^^
I have a file "media.txt" in this format: [Filename.mp3] [Filename.mp3]
and so on.. what I want to do is replace everything between [] with the random characters i generated.

import string

for line in open("file"):
line = line.strip()
if "[" in line:
print "[" +random_letters + "." +line[1:].split(".")[-1]
