title: unique information in each file or folder NTFS
body: <p>im working on a project where in i need to populate some files from the server and show them in a webrowser to the user. Where user would be allowed to do basic CRUD operation on the file
  The problem is that i cannot assign the name of the file/folder as <code>unique id</code> which i need in case a user deletes/renames a file i should be able to identify the file later.</p>
  
  <p>My question is that is there anything unique about any file/folder in <code>NTFS</code> that is unique about them and that can be used? and how that information can be accessed using <code>.NET c#</code>.</p>
  
  <p>Came across the <a href="http://msdn.microsoft.com/en-us/library/aa363788%28VS.85%29.aspx" rel="nofollow noreferrer">BY_HANDLE_FILE_INFORMATION structure</a>  but it probably needs me to <code>pinvoke</code>.</p>
  
  <p><strong>UPDATE 1</strong> - tried looking at the feasibility to use nFileIndexHigh and nFileIndexLow but they would need me to do a pinvoke and also this method cannot be used with folders
  one link when they mention folders <a href="https://stackoverflow.com/questions/10132686/unique-folder-identifier">Unique Folder Identifier</a> tells me that it isnt possible.</p>
