使用批处理文件递归重命名文件名+文件夹名称

@echo off
setlocal enabledelayedexpansion

set "oldname=old"
set "newname=new"

for /r %%f in (*%oldname%*) do (
    set "filename=%%~nf"
    set "fileextension=%%~xf"
    set "newfilename=!filename:%oldname%=%newname%!!fileextension!"
    move "%%f" "%%~dpf!newfilename!"
)

for /d /r %%d in (*%oldname%*) do (
    set "dirname=%%~nd"
    set "newdirname=!dirname:%oldname%=%newname%!"
    move "%%d" "%%~dpd!newdirname!"
)
