I’m a big GNOME fan and have been using it ever since it was first released.
Ofcourse, like all software, not all is good with the GNOME project also and some of the decisions made by the developers are just plain absurd to me. One such decision was making the Spatial mode on Nautilus as the default.
Nautilus, for those not familiar with it, is the default file browser/manager bundled with GNOME and the spatial mode basically means that each folder or file opens in a window of its own. There are other advantages to the spatial mode, I agree, but this is the one that I found the most irritating.
To make Nautilus behave and get rid of the spatial mode, open the gconf-editor application from the run menu and browse to the following key: apps -> Nautilus -> Preferences
Now, check the always_user_browser property.
That’s all. Now, go ahead and enjoy Nautilus and GNOME the way they’re meant to be.
