Feature to duplicate multiple files at once

This feature should allow users to select multiple files and perform a bulk duplication action.

It can be achieved in many ways. Here are some ideas.

1. Method 1: Multiple prompts for different files.

2. Method 2: Within a single prompt, many blank inputs for files at the right.

   Before:

   A.cpp ->
   A.js  ->
   A.css ->
   

   After:

   A.cpp -> B.cpp
   A.js  ->
   A.css ->
