Copy Files from folder as new name with numerical increments

Help & Support
1

Greetings , I'm trying to copy all files from a source and rename them numerically while keeping the extension.

copy E:\source* to "D:\destination" as NewName WHENEXISTS rename

This code does it but erases the extension (the extension can't be hardcoded so the button can target any filetype)

HELP!

Looking for (as a one liner):

NewName_01.ext
NewName_02.ext
NewName_03.ext

2

Got it!

rename from="Source*" pattern=".(..)" to="Destination\prefix \1" REGEXP number 001
