Answer 1

Run this from another folder, and the pushd is used otherwise the batch file will be renamed too. Change c:\mainfolder to your main folder name

@echo off
pushd "c:\mainfolder\"
for /r %%j in (*) do (
   rename "%%j" "[nilesh.uk.to]-%%~nxj"
)
popd

using renamer, you can do it in one command like this:

$ renamer --regex --find '^' --replace 'prefix-' '**'
