title: Windows Batch script - what does %%i mean?
body: <p>I wrote (using knowledge from Internet) script (batch file) to remove all folders and files inside a folder.</p>
  
  <pre><code>DEL /F /Q /S C:\commonfiles\*
  for /D %%i in ("C:\commonfiles\*") do RD /S /Q "%%i"
  </code></pre>
  
  <p>I just don't know what %%i means. Is it like i++ in C++?</p>
