How to retrieve the full file extension from filenames with 2+ dots in CMD?

Say you have a filename that has more than 2 dots in it, such as .symbols.nupkg. If you have a Batch script like this:

@echo off
setlocal EnableDelayedExpansion

echo %~x1

and you run it with the file in question, it will give you only the .nupkg portion. Is there any way to get the full file extension from such a string?

Thanks for helping!

In Windows, the file extension is defined to be the portion from the last period.

Anyway, if you do want to extract the portion from the first period, you could use the following code:

set "FILE=%~nx1"
set "FILE=.%FILE:*.=%"
echo("%FILE%"
