So aliases have been around almost as long as the Mac has. Before Mac OS, before Mac
OS 10 and they used to be very useful and the only way to do certain things on your
Mac. But there are so many other features now like the Dock, for instance, that make
it easy to access files and applications and things that you don't need aliases as much.
But they are still pretty useful. Just not as many people know how to use them. So let's
take a look at how they work.
So here I've got my documents folder and a bunch of subfolders in it. So let's create
an alias of the Docs folder. In order to do that I can Control click on it and there's
a Make Alias option there. But the typical way to do it is to drag somewhere else. So
I'm going to drag to the desktop. So the Docs folder I'm dragging to the desktop. I'm going
to hold down the Command key and the Option key both. I know I'm doing it right because
the arrow changes to this curved arrow which means it's not going to move or copy this
folder there. But instead make an alias. So I'll release and I get an alias to the Docs
folder. How do I know it's an alias? I've got that same curved arrow right there at
the bottom left hand corner. So what is an alias?
Well, here I am with the real Docs folder, the actual thing. I can double click and go
into it and see the contents of that Docs folder. Here I've got the alias. Double click
that and it will open up a new window and it will show me the same contents. It basically
is a shortcut to allow me to open up this folder. I'm actually looking in the real folder
now. That's the real thing. This is just an alias. So instead of having to go into my
Documents folder first I could get to it through the alias. In other words I can have all my
windows closed and this alias on the desktop and I can get into the Docs folder. As a matter
of fact I can even drag and drop something into this alias and it will act as if it's
the Docs folder. So that's what an alias does.
Now if you come from the Windows world you may find this familiar. It's called a shortcut
in the Window's world. Alias and shortcut are the same thing.
Now you don't just have to use this for folders. You can use this for files as well. So, for
instance, say I've got this Milestones.rtf file here. I can drag this to the desktop
as well, or to any folder. It doesn't have to be the desktop. Hold the Command and Option
keys down. I get the little curved arrow. Release and now I have a shortcut to Milestones.
So say Milestones is something I need to update daily and I want to have easy access to it.
I could go into the Docs folder and open up Milestones.rtf by double clicking on it. But
if the Docs folder isn't open, maybe I don't have this alias here, I could just have this
Milestones.rtf alias there. When I double click on it, it actually opens it up just
as if I double clicked on the real thing. So it allows me to have access to the real
file, kind of like just a link to it, instead of actually being the real file. It's important
to realize is if I delete this alias all I'm doing is just deleting the alias. The actual
Milestones file is still there in the Docs folder. So you can remove an alias and it
just removes the alias. The original is untouched.
Now you can do a lot with just this simple functionality. For instance here we are on
the desktop. I'm going to create a new folder. Shift, Command N to create a new folder. Let
me move that over there so you can see it. Let's call it Common Folders. Folders I need
to access a lot. This is a real folder. But I'm going to drag and drop using the Command
and Option key the Docs folder in there. I'm going to do the Images folder. Maybe this
Project B folder in there. Now when I look at the contents of Common Folders I see the
three alias in there. So I have easy access to these.
So, for instance, if I wanted to create or drag and drop a new file, so let's just create
a copy of this Milestones file here and let's call this copy New Milestones. Say I get here
and I'm like okay I want to store this somewhere. I can open up the Common Folders folder and
there are the aliases to these folders here. I can drag and drop that into Project B, like
that.
The cool thing is that these three aliases didn't have to be in the same place. They
are all actually in the Documents folder. But say Docs could have been in the Documents
folder. Images could have been in some other project folder somewhere else. Project B could
be three levels deep somewhere. But here all the aliases are all at the same level and
easy for me to get to. Maybe when I'm done with Project B I can get rid of it out of
this Common Folders thing here.
I can also drag and drop this special folder I made to the Dock and now I have access to
them right there which is really handy to be able to get to these folders pretty easily.
So that's just a little sample of how convenient you can make this for yourself by using aliases
on the desktop, using a folder of aliases on the desktop, putting a folder of aliases
or aliases themselves in the Dock. The Dock itself, when you're putting things here, is
kind of creating an alias itself so there would be not point, say, of making an alias
of Milestones and then putting it in the Dock. Just put Milestones in the Dock. But it would
makes sense, for instance, to have this Common Folders folder here. Let's just rename it
something like Frequent Items. I've got those two folders in it. But let me an alias to
the Milestones folder in there too. Command Option with the drag. Now you can see I've
got not only access to these two folders but access to this file in here. In the Dock those
three things are there as well. So I could actually just get to Milestones from the Dock
like that.
So you can use aliases for all sorts of things. There's lots of different ways. But the first
step is learning the basics of how to use and create aliases and what they are.
