Question

I need to rename files in some folder, like explained it needs to rename file names in one folder by removing first number of x characters and last number of x characters I set.
Can someone show me how to do that?

Answer 1

Here you go:

@echo off
setlocal enabledelayedexpansion
set X=3
set FOLDER_PATH=.
pushd %FOLDER_PATH%
for %%f in (*) do if %%f neq %~nx0 (
    set "filename=%%~nf"
    set "filename=!filename:~%X%,-%X%!"
    ren "%%f" "!filename!%%~xf"
)
popd

This script enters the folder (specified by FOLDER_PATH) and trims the first and last X characters from the filename of each file (leaving its extension as is). Modify X and FOLDER_PATH as necessary.
