  <p>Also, I have checked the size of C drive, and it almost full now, before doing this delete operation, the free space was 10GB.</p>
  
  <p>When I searched for the error, I found that backing up the transaction log will resolve the issue.I did the same and still, C drive remains full.</p>
  
  <p>What I can do to resolve the issue?</p>
