Identify thefts increased by 68% in 2021, and the majority of complaints were fraud related. Malicious hackers commonly use ransomware attacks to take data hostage until they get paid. Unfortunately, your unprotected files are easy targets for cybercriminals.
Considering this growing risk alongside our increasing reliance on electronic transfers, we need to take measures for better file security. Luckily, you can encrypt and password protect archive files on your computer, and this is particularly handy when you want to safely send and receive sensitive information.
Compressing your large data files into a single ZIP folder is a great way to transfer files between computers or to your family, friends, and colleagues. You can password protect your ZIP files to ensure privacy for sensitive data such as bank details, confidential files, or research data.
It’s important to password protect ZIP files to prevent cybercrooks or snoopers from accessing your private files and information. If a cybercriminals gets hold of your personal information or bank details, dealing with the consequences is far from simple. Protecting your files from the outset is a much simpler solution.
What is File Archive?
The five most common formats for file archiving are:
- ZIP. This file compression format is extremely popular because it’s the most easily accessible. Most operating systems have built-in support for extracting ZIP files so you probably won’t need to download third-party software to do so.
- RAR. While RAR is considered better than ZIP for file archiving, it requires third-party software to open and extract compressed files. Luckily, you can find many free tools for this online. RAR is also commonly used for error correction and file spanning.
- TAR. A TAR file archive can only be used with the official TAR application. It compresses files while preserving extraneous information such as permissions, dates, and user information. It’s mostly used with UNIX and Linux operating systems and is less popular than ZIP and RAR.
- TAR.GZ. This format is supported by most operating systems, including Windows, macOs, UNIX, and Linux. TAR.GZ is the archive format created by the TAR application and can be extracted with the 7-Zip application.
- 7z Archive. This format offers a high compression ratio, meaning it can condense large files into very small compressed files. It’s supported by the most recent versions of Windows.
What’s the Best Way to Archive Files and Folders?
You can archive and store files using several different methods, though some are more straightforward than others. The two most popular methods of archiving use compressed ZIP files or RAR files. Since these file types are used so frequently, it’s easiest to find reliable tools and information for compressing and retrieving them.
To securely store and transmit your archive files, we recommend always using a reliable VPN. When you connect to a VPN, your traffic is encrypted and routed through a secure server network. This ensures your data is safe from prying eyes. Try CyberGhost VPN to enjoy military-grade encryption when surfing the internet and sending important files.
How to Password Protect a Folder
When you encrypt your files and use password protection, you make the information inaccessible to unauthorized users. This usually involves an encryption key or password, which you’ll need to use to decrypt files and folders later.
We advise encrypting any sensitive or important files you archive, such as your personal, financial, or medical information. Keep reading to find out how to password protect and/or encrypt files using Windows, MacOs, and Linux OS.
Encrypting on Windows
Although you can’t password protect ZIP files or folders in Windows without downloading a program like 7-zip, you can easily protect your archive files. Windows has an in-built Encrypting File System (EFS) feature on a wide range of Microsoft Windows devices.
Windows encrypts files using an encryption key, then automatically saves it to the user account. This means you’ll only be able to access the encrypted file when you’re logged in to that specific user account. You can use this feature in a few simple steps:
- Find the compressed folder you want to encrypt and right-click on it.
- Click “properties” to open the property settings on the folder.
- Navigate to the “general” tab and then click “advanced” in the settings window.
- When the “advanced attributes” window opens, check the “encrypt contents to secure data” option.
- A confirmation box will appear asking if you also want to encrypt the subfolders. If you do, select “encrypt the file and its parent folder”, then click “ok”.

MacOS File Encryption
While it’s possible to encrypt a ZIP file on macOS without using any additional software, you’ll need to manually enter commands into your computer using Terminal. This might seem intimidating if you don’t consider yourself tech-savvy, but it’s very doable. Here’s how:
- Open Terminal through Finder > Utilities, and then click on the Terminal app. Alternatively, you can press Cmd + the space bar.
- Set the destination of the file you wish to encrypt and type “cd” plus the location of the file.
- Enter zip -er FILENAME.zip’ and replace “FILENAME” with the name of the file you’re encrypting. Now drag the file into the Terminal window and click “return”.
- You’ll then be asked to enter a password. This will be your encryption key, so make sure you write it down somewhere safe.
Linux File Protection
You can use the command line in Linux to password protect a ZIP file. Here’s how to do that in a few simple steps:
- Open the terminal and enter “sudo apt install zip unzip”.
- Enter “-e and –encrypt” to set a password for your ZIP file. You can also use the command “sudo zip –encrypt linuxhint.zip linux.txt debian.txt” to create a password-protected ZIP file in your current directory.
- Use the command “sudo unzip -r info.zip” to zip and unzip files.
You can also create a password-protected ZIP file using GUI. Visit the Linux instructions page for detailed information on how to do that.

- ️🔒 Change it to “.confidential” and it will automatically be hidden.
- ️🔒 To view the hidden file, simply click “show hidden” in your file manager.
Keeping Your Information Protected From Prying Eyes
It seems like every day our need to digitally transfer important files and information grows. That’s great, because it’s convenient, but it also puts your privacy and data at a high risk of theft. The good news: you can do a lot to protect yourself from snoops and malicious hackers.
Protecting important files containing your personal information, bank details, or other sensitive data is paramount to your privacy and security.
The simple methods we discussed in this article are a great start toward safer transfers — you can easily archive and password protect your files.
Major operating systems, like Windows, Linux, and MacOS include internal methods that provide extra security for your files, like password protection and encryption. That means you can immediately get some level of file protection without downloading any external software to protect or hide your files.

An archive file is a file that’s compressed for long-term storage (including cloud storage). You can compress many files of any size into a single file, like a ZIP or RAR archive. The resulting file size is a fraction of the original ones put together, so you’ll free up a lot of space.
While many people use separate apps to archive and password protect files, Windows, macOS, and Linux also have built-in systems to let you archive and password protect files (or encrypt them) without extra help. That said, using the built-in features can sometimes be more difficult than using apps like WinZip.
When you’re dealing with files containing personally identifying information (PII) on any device or operating system, you need to secure your connection. CyberGhost VPN makes it simple to encrypt your data and secure your connection with user-friendly apps for every major OS and device.
The most popular and efficient way to archive a folder is to create a ZIP or RAR file. This scrambles and compresses the data into a smaller file, making it easy to send and store. When you want to retrieve the data, you can use the “extract” function to get the original version of the file.
