Dolphin does not sort folders correctly if you select sorting by size. He arranges them randomly (maybe he only counts some files inside these folders, I do not know).

For more information, see the video.

Dolphin does indeed interpret the size of a folder as "number of items inside it". So, it works as intended.

It’s hard to calculate accurate sizes in bytes of folders on the fly, which is why there is a special KDE program called "Filelight". If you want to know which folders take up the most space, you can use that. Dolphin even has a link to Filelight in the context menu. :)

As far as I know, not even Windows uses the size in bytes to sort folders. (I’m not sure, it even uses item count)
