title: Max length of uploaded file name
body: <p>I have standard html form for upload files</p>
  
  <pre><code>&lt;form action="upload_file.php" method="post" enctype="multipart/form-data"&gt;
  &lt;input type="file" name="file"&gt;
  ...
  </code></pre>
  
  <p>What is maximum length of filename, which can be uploaded by user ?</p>
  
  <p>P.S.</p>
  
  <p>I'm saving file on server with modified name, but also need to keep original name, because I use original name at downloading that file.</p>
