Clearing IE9 cache

Have come across an issue lately with Internet Explorer 9. There is one temporary file seems not deletable regardless of how we tried with all available functions in IE.

1. Via F12 through development tool menu option
2. Via Internet Options menu option to delete all temporary files

At the end, we had to use PowerShell command to help clear IE temporary files, which finally deleted the file for us.

get-childitem "c:\Users\USERNAME\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\*" -recurse -force | remove-item -force -recurse

However, all applications that use these temporary Internet files need to be closed at mean time. Otherwise, the command will fail.
