Since KDE 4.1 it is possible to display the folders as a tree. In this mode a plus sign is shown next to the folder. Plus sign has been replaced by > symbol in newer KDE versions. By clicking on this sign the folder is expanded and all containing sub folders and files are also shown in the table but they are attenuated. By clicking the sign, which displays a minus now (or an arrow pointing downwards in latest versions), again the expansion is closed again. Of course the tree structure can be used for as many folders as wished. In latest KDE releases, the tree view is enabled by default, but can be deactivated via → → → with option .
