title: CMD instead of running command just opens it
body: <p>OS Win7, GAE 1.7.6, Python 2.7.3</p>
  
  <p>Working on Google app engine project with 2 other people, project leader gave us sample data via sampleData.cmd to run it inside.</p>
  
  <pre><code>nameOfTheApp\main&gt;sampleData
  </code></pre>
  
  <p>On other 2 computer this command starts to download files, on my just returns.</p>
  
  <pre><code>appcfg.py upload_data --config_file=bulkloader.yam...etc
  </code></pre>
  
  <p>In other words it just pop up in my text editor, and in CMD, but it doesn't run it.
  How to force this command to run?</p>
  
  <p>EDIT: Open sampleData.cmd with editor and c/p content in CMD </p>
  
  <pre><code>python appcfg.py upload_data --config_file=bulkloader.yam...etc
  </code></pre>
  
  <p>It returns python:can't open file 'appcfg.py' [Errno 2] No such file or directory</p>
  
  <p>ANSWER:</p>
  
  <p>Problem was that I associated .py files with my text editor, when changed to python.exe, it works...</p>
