title: Unzip archive to an existing directory structure
body: <p>I'm looking at bring the content of one WP blog over to another as I will be using WPML to server regional content instead of multiple sites. So not strictly a WP question, more command line.</p>
  
  <p>This may seem an obvious or stupid question, but if I bring over the other 'uploads' folder as a zip and unzip to the wp-content folder, will the contents merge into the existing folders or overwrite what is already there.</p>
  
  <p>If it's the latter, is there a switch I can append to ensure files are merged?</p>
  
  <p>Thanks in advance, 
  Tom</p>
