Is it possible to manipulate filename in batch?

Question

I have a script in batch that finds a filename from path. However, I dont't need the entire filename, only the first six characters. I thought that the following script would work, but it seems to not work with filenames.

set PL=%%~nG
set PL=%PL:~0,6%

It returns "~0,6".

is this happening inside for loop or if ? – npocmaka Jan 15 '21 at 12:30 — npocmaka, Jan 15 '21 at 12:30
then you need delayed expansion – npocmaka Jan 15 '21 at 12:40 — npocmaka, Jan 15 '21 at 12:40

As you confirmed that this SET is inside for loop you'll need delayed expansion

setlocal enableDelayedExpansion

for %%G in (something) do (
  set PL=%%~nG
  set PL=!PL:~0,6!
  echo !PL!
)
