title: How to change default directory for IDLE in windows?
body: <p>The installation directory is "d:\python2.7", and every time I open IDLE and click on menu File and Open item, the default directory is also "d:\python2.7". So I have to change the directory to where I want.</p>
  
  <p>Is there any way I can change it? Using configuration file or changing environment variable? </p>
  
  <p>I tried to add PYTHONPATH in environment variable, but it doesn't work.
  I also import os, and use os.chdir(), but it only changes the working directory, not what I want.</p>
  
  <p>Thank you.</p>
