title: Copy files without recreating subdirectories
body: <p>I have a directory that has about 100 subfolders and close to 2,000 files within those subfolders (up to 4 layers). The files are .txt or .log, and each extension has a unique file name.  I need to move or copy (whichever is faster) the files to the root of a different folder without recreating the subfolder structure like xcopy does. This is on Windows xp</p>
  
  <p>Thanks in advance.</p>
