Caja will manage your desktop. The MATE Desktop is an integral part of your experience and sits behind all observable items and is transparent to the user. In MATE like other Linux systems one has a HOME folder and inside that HOME folder lies the Desktop folder. It is there you can see what items the desktop contains. By default it contains the Trash folder as well as a Computer folder and removable media will show up if you for example plug in a USB stick or insert a CD/DVD.
