Snap remnants - what to do?

[Watford]

I installed two software to try them out. Two software that are to be used managing images. They installed through snap. Then I ended up uninstalling them using Software.
Now I still have these two snap, but empty (almost). What is the way to get rid of that, since of no more use ??

By the way I'm not a techie... can't figure what is the benefit of these snaps.....

The core in the Directory column is the name of the snap, so it’s the core snap, i.e. the base snap that all others depend on. You should be able to run

snap remove core

to remove it if you really want to.
