"calculate all sizes" missing

[Polgs]

Using MacOS High Sierra 10.13.1

I’m trying to display the sizes of folders so I open a Finder window and choose "View" -> "Show View Options" from where I should be able to tick "calculate all sizes”. That is what a number of different web sites have said should work.

However, I don’t see "calculate all sizes" as an option. What I do see on the “Show View Options” window is in the attachment.

Is this a new feature or is it just me? Maybe I have a switch incorrectly set somewhere.

That option will only appear if the Finder Window is in List View or Cover Flow View.

Thanks Gregg2. I should have guessed it would be something like that.
