Recursively Rename File Extensions Across Multiple Drives

Question

I have this for a batch file. I know squat about batch files.

FOR /r %%x IN (*.BMP,*.GIF,*.JPG,*.PNG) DO REN "%%x" *.jpeg

Which works fine locally. I need this to work across multiple drives (c:,d:,e:,f:,g:,h:,i:,j:).

Any help would be greatly appreciated. Thank you for your time and effort.

Cheers!

Here's a batch script that does what you want:

@echo off
setlocal

set drives=c,d,e,f,g,h,i,j
set exts=*.bmp;*.gif;*.jpg;*.png

for %%A in (%drives%) do (
cd /d %%A: && for /r %%B in (%exts%) do ren "%%~B" "%%~nB.jpeg"
)

pause >nul
endlocal & exit /b
