Question

I need to find the folder name of the batch file that I am executing. All the other approaches provide me with the full path.
I only need the parent folder name. Also, the other mentioned approaches use looping, which is quite lengthy and verbose for my needs.
Is there any method for finding out the parent folder name directly through the % parameters(or their combinations) ?

Answer 1

The direct answer to your question is “No”. There is no direct method using only expansion modifiers without using a FOR loop or CALL.

The referenced thread in your question pretty much has everything you need.

Here are two optimized techniques that are very similar to what has already been posted. Method1 should be the fastest:

Edit – I further optimized by removing the substring operation.
Edit2 – I substituted simple FOR in place of FOR /F

@echo off
setlocal

::method 1 using FOR
for %%F in ("%~p0\.") do set "method1=%%~nxF"
if not defined method1 set method1=\

::method 2 using CALL
call :getName "%~p0\." method2

::print results
set method
exit /b

:getName  PathWithTrailing\.  ReturnVar
set "%~2=%~nx1"
if not defined %~2 set %~2=\
exit /b
