title: Deleting file in Node.js
body: <p>I am using node in a Windows environment.
  When I use fs.unlinkSync(fileName), it seems to work. 
  After the unlinkSync statement is executed, if I do a fs.existsSync(filename) it returns false indicating the file does not exists, but when I go to the physical drive I can still see the file.</p>
  
  <p>At this point in time if I try and delete the file manually, it throws Access denied.
  However, the file is automatically removed from the file system only when I stop the executing  node script file.</p>
  
  <p>Is this the expected behavior?</p>
