title: iPhone Documents Folder Library/Caches Security issue
body: <p>I am developed one iOS Application. For security reason I downloaded All Audio/Video files to Documents folder under <strong>Library/Caches</strong>.</p>
  
  <p>For using iTunes the end user can't take this video backups. But some of the External softwares easily open the <strong>Library/Caches</strong> and download all files from this folders.</p>
  
  <p>My question is How to secure This Library/Caches folder or How to Not visibly stored files to Documents Directory.</p>
