Vista known for its annoying permission control. I struggled with this problem after reinstalling Vista. Some of my folders on D drive which seperated from C (where Vista located) could not be able to access due to lack of permission. Hey, I'm an administrator of this computer, am I ? Spinning with the problem hours, sometimes just want to get back to XP for god's sake. Fortunately, I found solutions to this problem which make Bill happier (for I don't have to be back to XP). All you have to do is just "take own" back your folders by doing the following commands. For Files: takeown /f file_name /d y icacls file_name /grant administrators:F For Folders or Directories (will perform action recursively): takeown /f directory_name /r /d y icacls directory_name /grant administrators:F /t Be patient while waiting for the opertion to complete. http://www.tipandtrick.net/2008/how-to-take-ownership-and-full-control-permissions-of-files-and-folders-in-vista/
