In the Macintosh, a simulated garbage can used for deleting files and folders. The trash can keeps the files intact in case the user wants to restore them, but can be "emptied" from time to time to save disk space.

Drag and Drop
The icon of a file or folder is dragged to the trash can and released. The trash can is also used to eject removable media by dragging disk icons onto it. See recycle bin.
