To recover space on your disk (or simply to keep your computer free of clutter), you can delete files that you no longer need.
In the Finder, open /Users/ username/Documents.
Tip: If the files are in a different location, open that folder.
Hold down , and then select the documents that you want to delete.
Tip: To see files displayed in a list, on the View menu, click as List.
Drag the files to the Trash.
On the Finder menu, click Empty Trash.
Any documents that you drag to the Trash remain on your disk until you empty the Trash.
