title: Is there any way to skip the root folder from where the search starts for preVisitDirectory when using Files.walkFileTree?
body: <p>Im using Files.walkFileTree and I'm also getting a call to preVisitDirectory for the root folder from where the search starts. Any way to skip this?</p>
  
  <p>For example: Files.walkFileTree for /test/ will first call preVisitDirectory with /test/ and then the test of the subfolders of /test/.</p>
  
  <p>Any way to make it start directly with the subfolders?</p>
