How to Zip a File on Mac
Converting any standard file to a compressed zip file the traditional way is effortless. You can do this to photos, videos, audio files, and documents, among others. Here are the steps:
- In Finder, look for the file or folder you want to compress and zip. Right-click or Ctrl-click on it.
- Select “Compress [name of file or folder].”
- Wait for the compression process to finish. Larger files may take time to end compressing.
- Once done, a new .zip file will appear in the same location as the original file or folder. You will also hear a system alert tone to notify you of the recently completed compression.
You can now send these compressed files or folders via email. You may also choose to delete the original files and folders if you want to save on disk space, but note that you can’t readily open or view the zipped versions. You’ll need to unzip them first (more on that later).

How to Change the Save Location of Your Zip Files
By default, a zipped file or folder will be saved in the same place where the original is saved. But, you may also choose a dedicated destination for all of your compressed files. It is done by opening the compression app. In Mac, it’s called the Archive Utility. A simple Spotlight search can easily find it. After searching for the app on Spotlight, open it. Click the Archive Utility drop-down menu at the top of the screen, then click Preferences. Select the menu named Save archive, then select into. Next, choose your desired destination.
How to Open and Unzip a Zip File on Mac
Opening a zip file to view its contents is pretty straightforward. Just double-click on the file, and it will open. The zip file can still be seen in the location folder, but an unzipped copy will also be created in the same location. Meanwhile, if were sent a compressed file in a format other than zipping, such as .rar, you’ll need to use an app to decompress it, such as The Unarchiver. You can get this app for free from the App Store. Once installed, the app automatically works pretty much exactly like your Mac’s built-in zip tool. Just double-click the archive file, then the files and folders will be extracted and saved in the same location as the archive file.
How to Enable or Disable a Browser From Extracting Zipped ‘Safe’ Files Automatically

In Safari, go to the drop-down menu. Locate and select Preferences, then click the General tab. Down below the window, you will see “Open “safe” files after downloading.” Leave the box checked if you want Safari to decompress these safe files automatically. Otherwise, untick the box.
How to Protect Your Zip Files With a Password
Now, here’s the more challenging bit. If you want to conceal some of your files, you can do so protecting it with a password. It is an excellent solution for highly confidential files since you probably won’t bother going through the quite complicated process to protect regular files. You may also do this for files that you are about to send through an unsecured messaging or mailing system. When you encrypt a zip file or folder, anyone who is trying to access the file using whether a Mac or PC will have to enter the password you create. To protect your zip file with a password, you’ll have to do it in the Terminal. As an example, let’s assume that the file is named softwaretested.jpg. Now, follow these steps:
- Open Terminal by going to Applications > Utilities > Terminal. You may also search for it on Spotlight.
- Type in cd Desktop then hit Enter/Return.
- Type in zip -e softwaretested.zip softwaretested.jpg, then hit Enter/Return.
- At this point, Terminal will ask you for the password. Type in the password you have in mind. Note that it will appear as if nothing is happening, but it’s designed this way so that the password will be concealed.
- When done typing the password, hit Enter/Return.
- The Terminal will ask you to verify the password. Type it again, then hit Enter/Return.
- Let Terminal finish the job. Status progress will be shown in the form of a percentage. When done, close the Terminal window.
A Note on Naming Your Zip Files
If you plan to protect a zip file or folder with a password, it is recommended that you don’t put spaces on the file name as much as possible. Telling the Terminal to password-protect a file with a name that has spaces will require you to do extra work. For instance, if your filename is software tested.jpg, you’ll have to type the code so as:
zip -e software tested.zip software tested.jpg
It’s not that difficult, but you should take extra caution whenever dealing with a file with spaces on its filename.
How to Password-Protect a Zip Folder
If it’s a zip folder you want to put a password on, change the -e extension to -er. For instance, zip -er softwaretested.zip softwaretested.
How to Open a Password-Protected Zip File or Folder

You've downloaded a file from the Internet, and it's in Zip format. Or perhaps a friend has emailed you a Zip file. How do you open a Zip file? What is a .Zip file anyway?
What is a Zip file?
Zip files are compressed archives. The term 'Archive' in this context means that the file may contain one or more files, or even folders, much like folders on your hard disk. 'Compressed' means that mathematical techniques have been used to reduce the space needed to store the files, so that the size of the archive may be much smaller than the size of the files it contains. There are many different compression techniques in use today. 'Zip' is the name given to the compression algorithm originally developed by Phil Katz. It isn't the best, and it wasn't even the first, but it is certainly the most widespread. And the name neatly describes a way of packaging up a file or group of files.
In short, Zip files are a space-saving way of storing single files or groups of related files.
Files in a Zip archive will decompress to exactly their original state. This is called 'lossless compression.' The compression methods used with JPG image files or MP3 music files are called 'lossy compression' because some of the quality of the original image or sound is lost during the compression process.
Zip files are used because they take up less space to store, and take less time to send or download. They are also a very convenient way to package and send groups of related files. However, the files must be extracted or unzipped from the archive before they can be used. Although some Zip / Unzip applications make it look as though you can open a file directly from a Zip file, in fact they must extract a copy of the file to a temporary storage area and open this temporary copy. Windows cannot open a file or run a program directly from a Zip file.
Opening a Zip file
If you're using Windows XP, then your operating system has built-in support for Zip files. They are described as 'Compressed (zipped) folders.' Just double-click on a Zip file and it will open in Explorer, just like a folder. Double-click on a file inside the compressed folder and you may be able to open that too (but really, Windows has extracted a copy of the file to another location and is opening that, as described above.) But if you right-click on items in a compressed (zipped) folder, you'll notice that the same options don't appear on the pop-up menu. This shows that it is not a real folder.
If you're using Windows 95, Windows 98, Windows Me, Windows NT or Windows 2000 then you'll need to install a special application to open Zip files. The application that is usually recommended to use is WinZip. WinZip became popular because it was the first ever Zip / Unzip utility for Windows. But with each new release it has become bloated with features and options that most people never use. Many people are totally confused by it.

BitZipper is an archive manager that lets you open not only Zip files but 30 other popular compressed and encoded file formats. It can create archives using most of these formats too, and it's also a fast and flexible backup tool.
BitZipper has a Wizard interface making it ideal for novice users with no experience of working with compressed files. It also has a Classic interface (shown right) for more experienced users. BitZipper is a solid and stable application that can handle the largest Zip archives without crashing, something the built-in Zip support in Windows often can't do!
BitZipper runs on Windows 2000, XP and Vista.
