Hello sirs, I'm looking for a way to change the filename of a file to another.

What I'm doing this for in twitch.
(load a picture on the stream)
basically it involves having an empty picture set, then changing it out with another, then changing it back 5 seconds after.

I'm not looking for this code however, just to change names of iles.

There's lot of ways in different languages so I hoped MIRC would have this function too.
