Make a Zip File

Need to send a bunch of files to someone through email? Want to save some space on your computer by consolidating all of your old pictures? Need to keep prying eyes away from important documents? Creating ZIP files will help you save space, organize your excess files, and encrypt sensitive material. Follow this guide to create ZIP files on both Windows and Mac OS X.

Steps

Windows

  1. Create a folder. The quickest way to create a zip file is to place all of the files that you want to archive into one folder. You can place multiple files and folders into the folder that you are creating the ZIP file from.
    • Rename the folder to whatever you want the ZIP file to be named.
  2. Right-click on the folder. Hover your cursor over the “Send to” option. This will open a new submenu. Select “Compressed (zipped) folder”.
    • You can also select multiple files in your file explorer, right-click on one of them, and then follow the above steps. The resulting ZIP file will contain all of the selected files and will be named after the file that you right-clicked on.
  3. Wait for the folder to be created. If you are adding a lot of files to the new ZIP file, it may take a few moments to create it. A progress bar will appear as files are added. Once the process is complete, the ZIP file will appear in the same location as the original folder.[1]

Mac OS X

  1. Create a folder. The quickest way to create a zip file is to place all of the files that you want to archive into one folder. You can place multiple files and folders into the folder that you are creating the ZIP file from.
    • Rename the folder to whatever you want the ZIP file to be named.
  2. Right-click on the folder. Click the “Compress” option. The folder will be compressed into a ZIP file. The new ZIP file will be located in the same location as the folder that you compressed.
    • You can also select multiple files in your file explorer, right-click on one of them, and then follow the above steps. The resulting ZIP file will contain all of the selected files and will be named “Archive.zip”.

Password-Protected ZIP File

  1. Download a compression program. Newer versions of Windows cannot create password-protected ZIP files without installing additional software. Compression software is available both for free and for purchase, though you don’t need anything fancy to create a protected ZIP. The most popular programs include:
    • 7-Zip
    • IZArc
    • PeaZip
  2. Create a new archive. Use your compression software to create a new ZIP file. Add the files that you want to compress. When you create the ZIP file, you will be given the option to enter a password. You will need to use this password to access this ZIP file in the future.
  3. Create a password-protected ZIP file in OS X. To create a password-protected Zip file in OS X, you can use the Terminal and you don’t need to download any other programs. First, place all of the files that you want to compress into a single folder, and then rename that folder to the name that you want your ZIP file to have.
    • Open the Terminal. This can be found in the Utilities folder in your Applications folder.
    • Navigate to where the folder that you want to compress is located.
    • Enter the command:
      zip –er <foldername>.zip <foldername>/*
    • Create a password. You will be asked to enter your password twice to verify it. Once you have entered the password, the ZIP file will be created.[2]


Tips

  • Press the Ctrl (Control) key on your keyboard to select more than 1 file at once in Windows Explorer or the Folder Navigation box in WinZip.
