If I have a...z, aa...zz,aaa...zzz files.
and I want to renames them to 1..26, 101..126,1001...1026.
Current way is to build a pair text, then load the text, then everything is done.
But make a pair text is not too easy, especially for the long one.
If the software pop up a panel, users paste the new name list in, then highlight the old one, then click. Task will be finished in seconds, if new list name already be served.
