windows - Replace part of a folder and its subfolders names using batch? -

-

i have folder structure on computer in form e.g. "photos" subfolders "summer 2012" "winter 2012" , have further subfolders. want place name "david" before each folder name i.e. "david photos" "david summer 2012" etc. . there batch file can write this? last attempt following:

for /d /r %%g in ("\\sampledrive\photos") (ren "%%g" "dan%%g")

however command window said syntax of command incorrect

thank in advance help!

using ren "%%g" "david %%g" rename folder "david \sampledrive\photos", cmd returns syntax incorrect. use %%~nxg instead, indicates folder, not path.

@echo off  /d /r "\sampledrive\photos" %%g in (*) (      ren "%%g" "david %%~nxg" ) echo finished! pause >nul
