title: Get full path from FileSystem
body: <p>I want to get the full path for a <code>FileSystem</code> which I created like this.</p>
  
  <pre><code>FileSystem fs = FileSystems.newFileSystem(Paths.get(folder.getRoot().getAbsolutePath(), "test.zip"), null);
  </code></pre>
  
  <p>Whatever I tried until now only got me an output like <code>/</code> and thats it, but what i really need to get is: </p>
  
  <pre><code>C:/Users/username/AppData/Local/Temp/junit9210120109362016454/Parent/test.zip/
  </code></pre>
  
  <p>Is there any way to get this information from the <code>FileSystem</code> object? I know I could just take the parameter I used to create it in the first place, but I want to be sure I don't mix anything up and I think it's better like that for a unit-test</p>
  
  <p>Based on the accepted answer I came up with this to solve my problem:
  <code>Paths.get(fs.toString(), "file.txt").toString()</code></p>
