Create and remove aliases on Mac
To make it easier to find a file, folder, app, or disk, you can create an alias for it and put the alias in an easy-to-find location. When you open an alias, the original item opens.
Create an alias
On your Mac, do one of the following:
Select the item, then choose File > Make Alias.
You can create as many aliases for an item as you want, then drag them to other folders or to the desktop.
Press Option-Command while you drag the original item to another folder or to the desktop to create an alias and move it in one step.
Add items to the Finder sidebar or Dock
The items you see in the Finder sidebar and the Dock are aliases that point to the original app, file, disk, or folder. For example, in the sidebar, Documents opens the Documents folder located inside your home folder. You can add your own items to the sidebar or the Dock.
On your Mac, do one of the following:
Add a folder, app, or disk to the Finder sidebar: Drag the original item to the Favorites section.
Add a file, folder, or app to the Dock: Drag the original item to the Dock.
Drag apps to the left side of the line that separates the recently used apps. Drag files and folders to the right side of the other line that separates recently used apps. If you moved the Dock to the side of your desktop, drag files and folders below the separator, and apps above.
Remove an item from the Finder sidebar or Dock
On your Mac, do one of the following:
Remove an item from the Finder sidebar: Drag the item out of the Finder sidebar until you see .
Remove an item from the Dock: Drag the item out of the Dock until you see Remove.
If you remove an item from the sidebar or Dock, only the alias is removed. The original item isn’t removed from your Mac.
Find the original item for an item in the Finder sidebar or Dock
On your Mac, do any of the following:
In the sidebar: Control-click the item in the sidebar, then choose Show in Enclosing Folder.
In the Dock: Control-click the item in the Dock, then choose Options > Show in Finder.
