title: Updating "Date Created" after copying files
body: <p>I have recently used iCloud for Windows (10) to download all pictures from iCloud onto my local machine. I then wanted to create a backup so I copy-pasted all (15'000) pictures onto an external hard disk.</p>
  
  <p>I noticed that because of the copy-paste action, the "Date Created" has -- in hindsight obviously -- been changed from the date that the picture was taken to the date / time of the copy action.</p>
  
  <p>Since the copy-action and before I noticed the change of date, I have put many hours into putting pictures in subfolders, etc. I would now like to put the original date/time back into the metadata.</p>
  
  <p>My idea is to make a dirlisting of the iCloud original archive, returning filename, md5 hash, and Date Created. I then want to write a script (Powershell?) to find the matching file in my subfolders, and update the date.</p>
  
  <p>A few questions:</p>
  
  <ol>
  <li>Does this seem like the best approach?</li>
  <li>Is there a better way to copy photo's in the future, keeping the original Date Created?</li>
  </ol>
  
  <p>Any help into the right direction whether this is a good idea with Powershell, would be greatly appreciated.</p>
