In the 2 years or so I have used Kubuntu 12.04, Dolphin has been my default file manager and Gwenview my default image viewer. Gwenview can also double up as a file manager, which can be useful when organising images and videos, but it provides less details (such as dates) on the files.
I have a number of icons on my desktop representing files or folders, and if I click on a folder it opened in Dolphin. A few days ago, it suddenly started opening Gwenview to see the folders - whether I inadvertently changed a setting, or this was done by a system update, I know not.
I've followed the advice in how-to-set-up-dolphin-as-default-file-manager, but it doesn't help; so I've uninstalled Gwenview. Ideally, I'd like Gwenview back as an image viewer, but Dolphin as default file manager. Is this possible, please?
