title: adding/editing new extended properties to the details tab in existing files
body: <p>I tried looking this on SO but all the questions that attempt to answer do not provide a full answer.</p>
  
  <p>I actually want to add a property to the details tab of an existing the file. File is of the sldprt extension. The property/value has to be visible in Windows Explorer.</p>
  
  <p>Not sure how this be done with Windows API Code Pack Shell or DSOFile? Any other solution is fine too. </p>
  
  <p>I'm using VS, C# on Windows 10.</p>
  
  <p>If someone could provide a detailed solution, I would be very thankful.</p>
  
  <p><strong>The perfect solution would:</strong></p>
  
  <ul>
  <li>Add the property to the file through dsofile, ADS, or whatever means possible.</li>
  <li>Edit to Windows Registery or whatever part of Windows that is responsible for showing the new property in the details tab of the file properties and in Windows Explorer</li>
  <li>Show how the property's value can be edited.</li>
  </ul>
  
  <p>This answer of this <a href="https://stackovearflow.com/questions/19947887/add-new-metadata-properties-to-a-file" rel="nofollow noreferrer">question</a> does not add attributes to the details tab nor Windows Explorer detailed view.</p>
  
  <p>I think it's possible since SOLIDWORKS (3d package) adds a property called <em>sw last saved with</em> to all SOLIDWORKS files. There are tons of other properties in the details window.</p>
  
  <p><strong>Please if you don't have the right solution, do not answer. Thank you very much.</strong></p>
