An alias is a tiny file that automatically opens the file that it represents. Although an alias is technically an icon, it’s actually an icon that opens another icon automatically. You can put aliases in convenient places, such as on the Desktop, to help you easily open programs and files that you access often.
In effect, Microsoft stole the alias feature from Apple (if you’ve used Windows, you may know aliases as shortcuts). However, aliases usually don’t break when you move or rename the original file; shortcuts do.
An alias is different from a duplicated file. For example, the Microsoft Word 2004 application uses 19.4 megabytes (MB) of disk space. A duplicate of Microsoft Word 2004 would give you two files, each requiring nearly 20 megabytes of space on your hard drive. An alias of Microsoft Word 2004, on the other hand, uses a mere 52 kilobytes (KB).
Aliases can open any file or folder on any disk from anywhere else on any disk — which is a very good trick. But aliases are great for many other reasons:
With aliases, it doesn’t matter. You can put the actual file in any folder and then create aliases of the file, placing them in any other applicable folder.
When you create an alias, its icon looks the same as the icon that it represents, but the suffix alias is tacked onto its name and a tiny arrow called a badge appears in the lower-left corner of its icon. Figure 1 shows both an alias and its parent icon (that is, the icon that opens if you open the alias).

To create an alias for an icon, do one of the following:
Presto! An alias appears where you release the mouse button. Better still, aliases created this way don’t have that pesky alias suffix tacked onto them.
Deleting an alias is an easy chore. To delete an alias, simply drag it onto the Trash icon on the Dock. That’s it! You can also Control-click it and choose Move to Trash from the contextual menu that appears, or select the icon and use the keyboard shortcut Command+Delete.
Deleting an alias does not delete the parent item. (If you want to delete the parent item, you have to go hunt it down and kill it yourself.)
Suppose that you create an alias of a file, and later you want to delete both the alias and its parent file — but you can’t find the parent file? What do you do? Well, you can use the Finder’s Find function (try saying that three times real fast) to find it, but here are three faster ways to find the parent icon of an alias:
