How to password protect a zip file

This guide explains how to password-protect ZIP files on a Mac, comparing the Terminal method with third-party apps like Archiver and BetterZip. It also covers creating standard ZIP files and opening password-protected ones.

MacOS lacks a built-in, user-friendly way to password-protect ZIP archives. The options are using the command line (Terminal) or a third-party application. This guide explores both.

Creating Standard ZIP Files:

Creating unencrypted ZIP archives on a Mac is simple:

• Single file/folder: Right-click, select "Compress."
• Multiple files/folders: Command-click to select, then right-click and "Compress."

Password-Protecting ZIP Files:

Three methods are detailed:

1. Using Terminal:

This is the native, albeit less user-friendly, method.

1. Open Terminal.
2. Navigate to the file's location using the cd command (e.g., cd Desktop).
3. Use the command: zip -e -r NewFileName.zip OriginalFileName (replace placeholders with actual file names).
4. Enter and confirm your password.

2. Archiver App:

Archiver offers a faster, more intuitive approach.

1. Download and open Archiver.
2. Drag the file(s) into the app.
3. Click "Archive," choose format and compression level.
4. Enable encryption, set a password, and click "Archive" again.

3. BetterZip App:

BetterZip provides advanced features and AES-256 encryption. Initial setup is required:

1. Set a master password in BetterZip's settings.
2. In Presets > Save, choose "Clean and Zip," select strong (AES-256) encryption, and set a password for future archives.

After setup, simply drag and drop files into BetterZip to create password-protected archives. BetterZip also allows password management for easier access to previously used passwords.

Opening Password-Protected ZIP Files:

Double-clicking the ZIP file will prompt for the password, using Archive Utility. Alternatively, use the unzip command in Terminal:

1. Open Terminal, navigate to the file's location using cd.
2. Use the command: unzip YourFileName.zip.
3. Enter the password.

BetterZip allows viewing and editing files within the archive without unpacking.

Conclusion:

While Terminal offers a native solution, third-party apps like Archiver and BetterZip provide significantly improved ease of use and enhanced security features for regular password protection of ZIP files on a Mac. Both Archiver and BetterZip are available through Setapp's trial.

FAQ:

• Password-protecting folders: Use the Terminal method or a third-party app.
• ZIP file won't open: Check the password, file corruption, software compatibility, and file permissions.
• Can't password-protect: Mac's built-in Archive Utility doesn't support this; use Terminal or a third-party app.
