CSS: How make the cursor to become a pointer on the input file?

Question

How can I make the cursor to become a pointer on an input file or an input text when you hover it?

My try but it does not work of course,

Answer 1

Cannot be done. The input type file is one of the most protected objects by the browsers. Some browsers allow you to do more things than others, depending on what they consider "safe".

You could use a flash button for it. In fact, there are very nice plugins written to make file uploading a nicer thing, such as Uploadify.
