So a Zip File is an archive containing one or more files. You would create a zip archive to
make it easier to transport a group of files, say sending it to somebody else
in an email message. It's easier to send one file than say a group of 30 or 40 files. This
also compresses the files making them smaller. However, today most files are already really
well compressed. If a document contains images they're probably compressed images like JPEG.
If you have an audio file or video file it's probably already really well compressed. So
you're only going to get a little bit more out of compressing a group of files into a Zip Archive.
Now to create a Zip Archive it is pretty easy to do if you are using macOS Ventura, macOS Monterey,
or even a few versions before that. There's a command you can get to right in the Finder. You
can just select a file and then Control Click, right click or two-finger click on a trackpad,
and then that brings up the Context Menu. Then go to compress. Simply select that and it will
create a Zip Archive from the file you had selected. It will use the same name as the
file. But you don't have to keep that same name. You can go in and change it to something else
and the contents will remain unchanged. Whoever unzips it on the other end will
end up with that file back regardless of what the actual zip archive is called.
Now you can also select multiple files. I'm going to do that using the Command Key to select
a second file and Command Key to select a third file. You could also use Shift to select a range.
Now with anyone of those I can Control Click on it
and choose Compress. It's going to create an archive using all the selected files.
Notice it calls this Archived.zip which you can now easily rename.
To Decompress zip files it's fairly simple. All you need to do is double
click the file in the Finder. What it actually does is open the zip file in
the default app which is an app you have on your Mac called Archive Utility. It's
part of macOS. As a matter of fact if you Control Click here and you see Open With,
you can see Archive Utility is the default. So if I double click you can see it quickly ran
Archive Utility. What Archive Utility did was unzip it. Since I had selected several files
to create this zip file it created a folder in the zip file and put the files in there.
So by unzipping it I get that folder called Archive and inside I can see those three files.
Now what if you wanted to use something else besides Archive. You can easily rename the zip
file archive but how do you rename the folder inside it. Well all you need to do for that is
actually create a folder. So here I've created a folder with three files in it. If I choose that
folder and use Compress notice it calls the Zip File by the name of that folder. Just like it
would do it if you selected one file. But now when you go to decompress it later, watch what happens.
I get that folder that was inside of it back. It didn't need to create an archive
folder to contain everything because it was just one item,
that folder. So if you want to use something besides the archived.zip name with the archive
folder inside it just create your own folder. Put the files in there and then zip that folder.
Now there are some settings for this. The settings are actually in
that Archive Utility. So use Spotlight with Command Space to find Archive Utility.app.
Run it. Then you'll see here the Archive Utility only has two commands. Create Archive and Expand
Archive. You can use Create Archive to select a file or folder and then create an archive like
this. It's a lot easier to do it in the Finder though. You could also expand archive and select
a zip file and expand it this way. Again it is easier to do this in the Finder by simply double
clicking. But what running Archive Utility by itself does get you is some settings. If you
go to Archive Utility Settings you'll see Unzip or Expansion settings here at the top and Zip
or Archiving options here at the bottom. Only the Unzip options here at the top actually work with
the Finder because the Compress command in the Finder is actually using some set options. So
changing these, like changing where the archive is saved, isn't going to effect the Compress
Command. But double clicking on a file actually runs Archive Utility and uses the settings here.
So if you'd rather have expanded files go to a specific directory rather than into the
same directory as the archive you can set that here. You could also change what happens after
you expand the Zip Archive. Instead of leaving it there you can have it moved to the Trash,
Delete It, or Moved to a folder of your choosing. You can also choose whether or not the expanded
items are selected after you Unzip and if Unzipping should continue. In other words if
there is a zip file inside the zip file should it continue expanding all zip files until it is done
or just do the top level Zip File and leave any zip files inside that as zip files. So if I change
this to Move Archive to Trash and then I go to Expand this you'll see how it works differently.
It expands it. I get the results but that Zip File is now here in the trash.
Now one thing we're missing with Archive Utility is the ability to make a Zip File
that has a password set. It's encrypted. Well, if you go to Archive Utility Settings
there's a Save Format here called Apple Encrypted Archive that will allow you to
add a password and it will encrypt the file. But you won't get a zip file from
it. You'll get an Apple Encrypted Archive which probably won't be useful unless you're sending
it to somebody else also using a Mac. But you still can create a password protected
Zip File on your Mac. You just need to use Terminal to do it. Now even if you don't
like using Terminal this is a fairly simple task to do in Terminal. Let me show you.
I'm going to use Spotlight to find and launch the Terminal App. So the first thing we want to do is
we want to go to the Directory we are using right here. So I'm going to do cd for change directory.
I'm going to drag in the folder icon from the Finder window here. This saves me from having to
type this out. It's basically just my home folder, documents, files. So now I'm actually in this
directory. Now it is much easier to work. I can do zip to zip the files. I can do dash and then e
for encryption. This will prompt us for a password and encrypt the zip file with that password. r for
recursion which means that if I include a folder, it's not just going to include the folder but the
contents of the folder, and in fact if there is a folder inside that folder it will include the
contents of that folder and so on. So in other words the normal way you would expect it to work.
Now just give it a name for the archive. So I'll call it stuff.zip. Now I'll just type the names of
the files I want to include. So let's do Test.rtf, let's do Test.numbers, and let's do Jack.jpeg.
Let's include also the folder of stuff. I'm going to put that in quotes since there are spaces,
like that. I could always have selected these items here
and copied and then pasted the names. But I don't necessarily want to drag and drop
because that gives me the full path there. That would actually create problems in the zip file
because it's going to include that whole path. So let's just keep it simple like this. I'll
hit Return. It's going to prompt for a password. So I'll enter it once. A second time to verify.
Then you'll see it working adding each of those files there. You can see here I get the results.
Now decompressing you don't need Terminal or anything special. Just double click and
Archive Utility will handle passwords just fine even though you can't create
the files with passwords you can unzip them. So I'll enter the password and then Return
and it's going to create a folder with that same name
and under it I can see those files. I can see that folder and the files that were in that folder. To
make it a lot easier I really recommend creating a folder to contain everything that you want to
zip up and then just having one thing that you can add here instead of having to type multiple names.
So there's how to zip files, unzip files, and even create a password
protected zip file on your Mac. Hope you found this useful. Thanks for watching.
