title: how to configure cygwin Local Package Directory
body: <p>I have to change my cygwin Local Package Directory, which happen to be earlier as <code>C:\Users\username\Downloads</code>.</p>
  
  <p>Folders like <code>http%3a%2f%2fcygwin.mirror.constant.com%2f</code> are all in place in my new directory for Local Package Directory.</p>
  
  <p>How to do that? (I cannot find, where cygwin stores the config.)</p>
  
  <p>Running setup from new location tries to install all over again instead from continue using earlier packages from the internet.</p>
