Need File Manager like Directory Opus; also Backing up to External Drive question

Except--what do you do if "list view" does not show a triangle next to the folder--just an icon?
It was there and now it's not.
Edit: Oh--I see there was a discussion about this above. (A lot to keep track of).
Yes, it does do this and it doesn't. Hmm

Just tried it...
If you have it set to "Arrange by Name" it wont show the triangles. I have mine set to "None". Actually, if it's set to Arrange by anything it wont show the triangles.
Wonder why it does that?

That fixed it! Thanks, Craig. Now I wonder, like you, why that is? Bug? Feature?

Probably a feature. I'm sure someone somewhere has a use for that.

Thanks Craig. That's helpful.
