What does /ownall exactly do?

Hello

What does /ownall exactly do? Description is: "Claim all property." (thats all)

a.) Claim only the connected property of a player from the tile you are standing on?

b.) Claim the whole world property of each and every player?

thank you in advance

Thank you, thats what i thought.

In the tool admin utils it says "/unclaimall username" will delete all claim from a player on a world, so you dont have to search for it.

but it doesnt seem to work, is that so? Or did i forget something?

example: username is carl

/unclaimall carl

Is there anything missing?

Thank you in advance
