Get last token from string in batch script

I am working on a batch script, and I need a way to remove the lowest-level directory from a full path string. So for example, if I have:

C:/dir1/dir2/dir3

I would like my batch script to return "dir3." This string, C:/dir1/dir2/dir3 is passed in by the user and set as the variable "FullPath".

I looked over the answer here, which appeared to be a similar problem, but the solutions there didn't make any use of delimiters. And, the closest I've gotten to solving this is this code:

for /f "tokens=(some number) delims=\" %%a in ("%FullPath%") do echo Token=%%a

...this can echo any token I specify (I will eventually be setting this token to a variable, but I need to get the right one first), but I don't know how many tokens there will be, and I always want the last one in the string, as following the "\" character.

How can I edit this line of code to return the final token in the string?

I had a similar case, where I wanted only the name of the file from a link address. This seemed to do the job:

@echo off
set PYZIP=https://www.python.org/ftp/python/3.8.6/python-3.8.6-embed-win32.zip

for %%x in (%PYZIP:/= %) do set PYZIP_FILE=%%x
echo %PYZIP_FILE%

returns: python-3.8.6-embed-win32.zip

if the tokens are separated/delimited by forward slashes ("/"), the last token is:

set b=C:/dir1/dir2/dir3
for %i in (%b:/=\%) do echo %~ni

I solved in this way:

for %%x in (%fullpath:\= %) do set last=%%x

This uses the same logic as the last answer but it does the standard for loop changing the delimiter from \ to space with the %var:=% syntax. It's a trick to obtain the effect of for /f "delims=\", using for instead of for /f which does not loop like plain for.

for %%a in ("%fullpath%\.") do set "lastPart=%%~nxa"

That is, use a for loop to get a reference to the full path and from it retrieve the name and extension of the last element
