[CentOS] file managementttttttttttt

Last week, I installed CentOS 6 yet again.
I took the default desktop: gnome.
Whenever I open a directory, I get a new window.
That gets rather annoying,
especially when I have to drill down several levels.
Is there around that behaviour?
If it's in edit->preferences, I didn't find it.
Eventually I expect to change desktops.
Until then, any ideas?
