Answer 1

The idea of DaDummy worked out in more practical reuseable functions. Also the first character of the _full_path is now included.

set map=D:\test1\test2\test3\test4.txt
call:get_parent_path "%map%"
echo full_path is %_full_path%
call:get_parent_path %_full_path%
echo full_path is %_full_path%
call:get_last_path %_full_path%
echo last_path is %_last_path%
goto :eof

:get_parent_path
set "_full_path=%~dp1"
:_strip
if not "%_full_path:~-1%"=="\" if not "%_full_path:~-1%"=="/" goto:_strip_end
set "_full_path=%_full_path:~0,-1%"
goto:_strip
:_strip_end
exit /b

:get_last_path
set "_last_path=%~nx1"
exit /b

::result:
::full_path is D:\test1\test2\test3
::full_path is D:\test1\test2
::last_path is test2
