Hello,

This code below changes .dll files into .bak files in BaseFolder and its subfolders.
I just want to exclude files whose folder containing them has a specific name, let's say there is a subfolder called "DoNotModify".

Code: Select all

set folder=My\BaseFolder\
pushd "!folder!"
set "folderpath=!cd!"
if not "!folder:~-1!"=="\" set "folder=!folder!\"
	
	for /R %%f in (*.dll) do (
		ren "%%f" *.bak
	)
	popd

Use string replacement to test if the folder exists within the folder path.

Code: Select all

for /R %%G in (*.dll) do (
     set "foldercheck=%%~dpG"
     IF  "!foldercheck:DoNotModify=!"=="!foldercheck!"  ren "%%~G" *.bak
)

Hmm for some reason with this nothing happens, even if subfolder name is different, no files are being renamed.

I had the logic backwards. Remove the NOT.

Right, it works now, thank you!

You should probably change the rename to

Code: Select all

ren "%%~G" "%%~nG.bak"

The "n" modifier is the file name only. No path no extension.
