Many people after I make some minor modifications in their Macs appreciate to have icons to delete files and folders and add new folders in the Finder Toolbar. In the default installation of Mac OS, these icons and related functions are note visible.

To do so, just open any folder to show a Finder window and click on View -> Customize Toolbar in the Finder menu:

Costumize Toolbar Finder
Costumize Toolbar Finder

Drag the icons “New Folder” and “Delete” to the Tool Bar:

Another interesting icon is “Path”. It shows where the opened folder is located and allows navigate upper in the folder tree.
