title: Does Eclipse store any information out of its directory?
body: <p>I have used Eclipse Indigo (C/C++) for sometime along with PyDev Plugin (for Python). As I messed up with the IDE (tried to tweak some core files, for fun!), I thought to install a fresh one and this time I downloaded Eclipse Indigo (for Java).</p>
  
  <p>Eclipse (C/C++) was placed in C:/</p>
  
  <p>Eclipse (Java) was even placed in C:/</p>
  
  <p>Now when I opened Eclipse (Java), I observed two things:</p>
  
  <ol>
  <li>The Eclipse's title bar still showing <code>&lt;C/C++ Eclipse&gt;</code></li>
  <li>There was a python's project file still opened up which I worked on Eclipse C/C++ IDE. Also, there was an PyDev's error popped up (mentioning it wasn't installed).</li>
  </ol>
  
  <p>I have verified "Installed Plugins" list and didn't find any plugin related to C/C++ or python.</p>
  
  <p>Now, I have got one question:</p>
  
  <p>As I searched over google and found that Eclipse doesn't store anything beyond its directory, How does this above things are showing up??</p>
  
  <p>There might be some Temp/ Cache files stored. However, I searched my drive with "Eclipse" and "PyDev" as keywords and found nothing.</p>
  
  <p>I even searched for registry keys but couldn't find anything.</p>
  
  <p>What exactly is happening and how do remove Eclipse completely?</p>
