title: Get relative path of files in sub-folders from the current directory
body: <p>Is there any straight-forward way (by use of cmdlets or .NET classes) to obtain only the relative path of a file in a sub-folder from a given path?</p>
  
  <p>eg current folder is <code>C:\MyScript</code> and there is a sub-folder called <code>Data</code> with a file <code>Test.txt</code>, so I would like to see <code>Data\Test.txt</code> instead of <code>C:\MyScript\Data\Test.txt</code></p>
