In your code, "args[0]" means the first element in the "args" array. And the "args" array, because it is the parameter of your "main" method, is the array of parameters which you typed at the command line after the class name.

So the error message says that you didn't type any parameters at the command line. Try again, this time including the parameter.
 
I agree. Here's the link: http://aspose.com/file-tools
