Dolphin, right-click "Create new folder" missing

I am running dolphin 24.08.3, KDE plasma 6.2.3, using btrfs file system.

Normally, when I want to create a new directory from dolphin, I right click in the file list panel and choose “Create new->folder” (at least, this is what I think I used to do). Today, I was surprised to discover that I can’t find that option in the right click menu.

What I see in “Create new” is a handful of file types at the bottom (Text file, empty file, etc), but above that is a very long list of existing directories and files - so long that it extends off the top of my screen. “Create new->folder” may be at the top of that list, but I can’t get it to scroll down to see the beginning.

It is not obvious to me what is supposed to happen if I pick one of those directories, but I decided to try it. It appears to have made a copy of the directory I picked, and its files, but a few observations:

First, it happened too fast to have actually copied all the files in the target directory.

Second, editing one of the new files in the copy revealed that it did NOT make a symlink or hardlink to the target directory.

So did this make a btrfs COW copy/reference to the target directory? That is the only thing that makes sense to me.

Anyway, I put a “Create folder” button in the dolphin toolbar to recover that function.

You are running into 494679 – Dolphin populates "Create new" menu with the content of home dir more details in Dolphin "Create New" context menu is just showing contents of my Home Directory - #5 by solarisfire

This is fixed in KDE Frameworks 6.8, if you update this should be fixed.

That’s btrfs magic, copy is “free”/instant, it is implicitely a sort of symlink that can diverge independently.

And KDE software will use reference copy by default when the filesystem supports it.

Anyway, I put a “Create folder” button in the dolphin toolbar to recover that function.

You can also use the shortcut Ctrl+Shift+N.

Thank you - that explains this. Sorry for the duplicate post - I thought I looked to see if this had been discussed here, but obviously I missed it.

Anyway, at least I made a very cool discovery - that dolphin is using btrfs features when I copy files. Very nice.
