.bat将文件夹/子文件夹中的文件重命名为特定名称

Question

I need a .bat file that can go into a folder with many sub-folders and rename every .iso file to "Game.iso". I had a way to do it but I cant seem to find it anymore and I lost the damn file :(.

Example:
-Main DIR
--A
---file name.iso
--B
---file name.iso
--Z
---file name.iso

What I want to be like when I run .bat file:
-Main DIR
--A
---game.iso
--B
---game.iso
--Z
---game.iso

That is really my main concern. That would be super amazing and I would appreciate it tremendously.

Answer 1

Simple:

for /r %%a in (*.iso) do (
ren "%%~a" "%%~paGame.iso"
)

And that should work. Simply run it from the Main Dir
