Windows – Renaming multiple files inside a folder using Windows batch commands

batchrenamewindows

This is taking the post located here and spinning things up a bit.
As typical, I'm trying to rename several images inside a folder to be the name of the folder they're in and then add the suffix "photo1", "photo2" etc.

In other words, I'm trying to go from here: 

Folder1
  IMG_001.jpg
  IMG_001.jpg
  IMG_003.jpg

To here: 

Folder1
  Folder1_photo1.jpg
  Folder1_photo2.jpg
  Folder1_photo3.jpg

Catch is there several hundred of these "Folder" folders, and each one of these will need to have the photos inside of it renamed.

I know there is 3rd party software out there that can do this but I'm looking for a way to run this as a Windows .bat.

If anybody has an idea please share. Thanks for your time.

Assuming all folders are in the same root folder, and all images match the template IMG_n.jpg, then the following one liner should work on the command line:

for /d %A in ("yourRootPath\*") do @for %B in ("%A\img_*.jpg") do @for /f "tokens=1* delims=_0" %C in ("%~nB") do ren "%B" "%~nxA_photo%D.jpg"

Don't forget to double up the percents if you use the command in a batch script.
