How to Open and Create Zip Files on a Mac

Oftentimes, when you download files from the internet, you may find out they are compressed. Such files allow for sending multiple pictures or documents in one go. Various OS offer different applications for the purposes of compressing and decompressing files.

 

In this guide, we’ll have a look at how to create and open compressed files on a Mac.

 

In order to create a zip file, Macs offer an in-built app installed by default—the Archive Utility tool. The app is able to open files with a .zip extension. There is also an application called The Unarchiver, which is also designed for Macs. You can download the app from its official website.

Here’s how to open .zip files on your Mac with Archive Utility:

  • double-click on the zipped file
  • Archive Utility will unzip the file automatically and place it into the same folder where the zipped file is located
  • find the unzipped file and open it by double-clicking on it

Unfortunately, if the compressed file has .sit formatting, you will not be able to decompress it with a default app, so you will have to use third-party apps like Stuffit. You can download a free version of the application from the official website.

How to change Archive Utility preferences

While Archive Utility is running, right-click on the application’s name. In the context menu that opens, choose Preferences. When the Preferences window opens, you will see a number of available options. You can choose the route for the uncompressed files and specify your further actions with the uncompressed files.

 

Automatic deletion of the archived files after they are uncompressed is a real time-saver. It will save your computer from junk files clogging up your hard drive.

How to enable password protection for zip files

Sometimes, you might need password protection for your zipped files to prevent unauthorized access. There are two options to make a password-protected file. The first option is to use the Terminal. If you are familiar with the command line you can type in zip -e archivename.zip filetoprotect.txt, then enter and verify the password. 

 

The second way is arguably easier—use the in-built Archive Utility, which has the same functionality of assigning a password.

How to extract zip files with Terminal

If the compressed file is in the .tar or .tgz format, in order to decompress it you should use the in-built Mac application called Terminal. Your actions should be as follows:

  • open Terminal
  • use the cd command to indicate where the decompressed file should be located
  • type unzip file.zip into the Terminal to run the zip command

How to restore deleted zip files

If you don’t like to keep unnecessary files on your hard drive, photos you may have a habit of cleaning your PC from this type of junk. During the clean-up, you may accidentally delete important zip files. Luckily, there is a way to restore those files. Read a detailed guide on recovering deleted Mac files.
