My desktop environment is KDE, the OS is Debian running in a Compaq laptop.
I have a small but very annoying problem that I couldn't find a solution.
I could not find a way to configure the window that opens files in firefox, gnumeric or most other applications. I don't want for instance to see the hidden files and folders. Where this can be configured. Tried already everywhere in Kcontrol. In gnome it is quite easy to configure the window. It is surely something quite trivial, but I couldn't figure out how to do it.
Any help would be appreciated,
