The default file manager in Ubuntu (Unity and GNOME) is Nautilus. In Kubuntu and KDE, it is Dolphin. You can install other file managers, such as Konqueror, and Thunar.
use VMware player to install Gnome and KDE
The GNOME Display Manager (GDM) and KDE Display Manager (KDM) are X display managers that allows a user to start an X session on an X server. In other words, the display manager shows the login screen when nobody is logged in. After it checks your username and password, it hands off the work to the actual display manager (e,g, GNOME, KDE, Xfce, LXDE). GDM uses the GTK windowing toolkit, while KDM uses the KDE counterpart, Qt.
Gnome. If you want KDE, you can use Kubuntu, the KDE derivative of Ubuntu.
Ubuntu - GNOME Kubuntu - KDE Xubuntu - Xfce Puppy Linux - JWM Damn Small Linux - JWM, Fluxbox Fedora - GNOME (default) OpenSUSE - KDE (default) Debian - GNOME, KDE, Xfce Red Hat Enterprise Linux - GNOME Linux Mint - GNOME Xandros - KDE PCLinuxOS - KDE
Gnome There is a KDE version named Kubuntu, however
Desktop environments.
Everything will still work. However gnome applications do not interact with the desktop environment of KDE as well as they would with gnome. The differences will be mainly superficial. You can always remove the gnome applications later and replace them with kde ones if you want.
Ubuntu uses GNOME by default. However, a KDE version is available, named Kubuntu. It doesn't have all the bells and whistles of its GNOME counterpart
there is a program called dolphin (not to be confused with the KDE file manager) that is available via playdeb.net
