title: Can't get access to a disk for compression - UnauthorizedAccessException
body: <p>I need compact all the folders of my E:\ But when i try with this code, i get this access exception.
  I'm new on programming and are trying learn how a i can do this work.
  I'm using the dotnetzip for compact the directories inside E:.
  Some parts of the code are just copied, i know that... but i'm trying learn how to do work.</p>
  
  <p>I already tried some others solution for solve the problem answered here.
  Like add a manifest to the project who requeireAdministrator permissions to run and insert a Access Control Rule to modify the security of E:\ Something that i notice when do this is my user have permissions removed from the subfiles and directories of E:\ But without this access rule the same exception keep existing.</p>
  
  <pre><code>        try
          {
  
              ZipFile zip = new ZipFile();
              zip.AddDirectory(@"E:\");
              zip.Save(@"C:\Users\vitorbento\Desktop\backup.zip");
  
              Console.WriteLine("Compactação concluída");
              Console.WriteLine("Done.");
          }
          catch (UnauthorizedAccessException)
          {
              FileAttributes attr = (new FileInfo(DirectPath)).Attributes;
              Console.Write("UnAuthorizedAccessException: Unable to access file. ");
              if ((attr &amp; FileAttributes.ReadOnly) &gt; 0)
              Console.Write("The file is read-only.");
          }
