Element folders in .tpl file

Hi everyone
I’m a novice with harmony but I’m trying to keep my tpl files as small and clean as possible.
I notice that when you have a .tpl file that has been revised a few times many folders appear in the elements folder.
They contain a lot of .tvg files that are not in use - how do i get rid of them?

I tried “Removed unused files” but that doesn’t make a difference.

Does it make a difference if I just manually delete them in finder will i make the .tpl unusable?

I’ve been googling this for more time than i’d like to admit.

Any help is much appreciated.

Thanks!

You can right-click the template in the Library to “Edit Template”.
Then from the menu-File-Remove Unused Files.
