How to get the path of the script batch in Windows?
Source : Stack Overflow [windows].)
%~dp0 will be the directory. Here’s some documentation on all of the path modifiers. Fun stuff 
To remove the final backslash, vous pouvez utiliser the :n,m substring syntax, like so:
SET mypath=%~dp0
echo %mypath:~0,-1%
I don’t believe there’s a way to combine the %0 syntax with the :~n,m syntax, unfortunately.
