Getting the file extenseion

[eddyq]

In at .BAT file, to get a file extension I am doing this:
for %%1 in (file_name.ext) do set ItemExt=%~x1

But that keeps the dot so the extension comes out ".ext". I want it to be just "ext".

Is there a way?

[Squashman]

set itemext=%itemext:~1%

[eddyq]

It worked!

Thanks
