you have to know javascript.
the best way IMO is indeed to use diff tpl, to avoid changing the template.
i would do something like this
[+more onload]
$('#actions center').append('<button>my rename</button>').click(function(){
// here goes what you want it to do
});
thank you for your reply, i just found the rename function is easy to move one file to another folder
just like ./subfolder/currentselect.file
so how can i add this function as another button name "changefolder"
just add " ./subfolder " in the code
tnank you very much.
