Version: 4.0.0 (using KDE 4.0.0) Installed from: Gentoo Packages Compiler: gcc 4.1.2 OS: Linux Because there are konqueror and dolphin now in KDE 4 it should be possible to set your default filemanager in kcontrol/systemsettings. A good place for this would be "Default Applications" in the personal category.

Implemented just that today. Will be in KDE-4.2. Meanwhile you can type keditfiletype inode/directory and do just the same there :)
