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.
