ADDITIONAL INFORMATION
The SMB shares that I have are mounted using /etc/fstab and cifs type. Not sure if this bug occurs for SMB4K mounted shares. I have also raised the limit on remote previews, to no affect.

Do you use smb:// url or a fstab/mount ?

> 2. Change the icon of a folder in that SMB share
How did you try to do it (which way, which dialog/menu)

I tested the `smb://` and the UI doesn't let you change the folders (neither, context menu, new folder or folder property).

Currently the custom icons are save to the hidden directory .directory, that won't be hidden on windows and "pollute" the file list.

We are planning to remove this .directory file to a filesystem extended attribute instead.

So the issue might be that the feature is exposed despite being on a samba share.

This is duplicate of https://bugs.kde.org/show_bug.cgi?id=507493

SMB reports zero-sized directories and so .directory files are ignored by frameworks/KIO.

I verified that removing the relevant size check KIO/dolphin respect .directory in SMB shares.

Then that's an easy MR.
It would need some nuance this 0 size check is there for some reason presumably.
