Can you explain me, please, if it's possible, how to change the extensions ?
I have a lot of videos / clips , and they are in different extensions, like .avi / .mpeg / .vmw / .flv and so on
I wanna open them all with my KMPlayer. I tried this way :
right click one file, properties / change / and i selected KMPlayer. But that's only for this kind of file.
