title: What is a working copy and what does "switching" do for me in Tortoise SVN?
body: <p>I have a software app and I've hit an important milestone, version 2.0.</p>
  
  <p>I decided I want to tag this version as "Version-2.0" so I have named this snapshot. I also created a "Version-2.0" branch in case I need to fix anything and merge it back into my trunk.</p>
  
  <p>After reading through the Tortoise SVN help file, it informs me that I can switch my "working copy" to a newly created branch.</p>
  
  <p>What does this mean?  </p>
  
  <p>Presently, I have:</p>
  
  <blockquote>
    <p>/Project/Trunk/<br>
    /Project/Tags/<br>
    /Project/Branches/</p>
  </blockquote>
  
  <p>All checked out. So what would be the point of "switching"?  Currently, I just go to my /trunk folder and do my work.  And when I made my tag and branch, it created folders in my /Tags/ and /Branches/ folder after I did an update.</p>
  
  <p>Why wouldn't I just go to /Branches/Experiemental-v3.0/ and do my work there if I wanted to?</p>
  
  <p><strong>Can someone explain the concept of "Working Copy" and "Switching" to me?  What am I missing?  Do people generally not have the whole repository checked out, is that it?</strong></p>
