Windows 10 File Explorer can create and open ordinary ZIP archives, but it does not provide a built-in option for creating a password-protected ZIP file. If you need a ZIP archive protected by a password, use a reputable archiving application that supports encryption, such as AES encryption. Do not assume that simply compressing files makes them private.
Windows 10 Support Note
Standard support for Windows 10 ended on October 14, 2025. Eligible Windows 10 version 22H2 consumer PCs can receive Extended Security Updates through October 12, 2027. On compatible hardware, plan to move to Windows 11.
How to Password Protect a ZIP File in Windows 10
- Install a trusted archiving application that supports encrypted archives. Download it from the developer’s official website rather than a third-party download mirror.
- Select the files you want to protect. Make sure you are working with copies if the originals are important.
- Create a new archive. Choose ZIP if the recipient specifically requires that format.
- Open the application’s encryption or password options. Choose strong encryption such as AES when the application and recipient support it.
- Enter a strong, unique password. Do not reuse an important account password.
- Create the archive.
- Test it before deleting anything. Close the archiving program, reopen the archive, and verify that protected content cannot be extracted without the password.
- Share the password separately. If you send the archive to another person, avoid sending the password in the same message when practical.
Why File Explorer Is Not Enough
The built-in Windows 10 compressed-folder feature is useful for reducing file size and grouping files, but it does not provide a normal password-encryption option when creating ZIP archives. Older Windows or third-party tutorials can make this confusing because some archive programs integrate their own commands into File Explorer.
Encryption Method Matters
Traditional ZipCrypto password protection is widely compatible but is much weaker than modern AES-based archive encryption. When security matters and all recipients use compatible software, prefer a strong modern encryption method. If compatibility is more important, confirm which encrypted ZIP formats the recipient’s software can open before sending the archive.
A Password Does Not Protect Unencrypted Originals
Creating an encrypted archive does not automatically erase or encrypt the original files. If the originals remain on the PC, anyone with access to those files may still read them. Decide separately whether the originals should remain, be stored on an encrypted drive, or be securely handled according to your needs.
What If You Forget the Password?
Strong encryption is designed to resist unauthorized access. That also means there may be no practical recovery method if you lose the password. Store important passwords in a reputable password manager or another secure location.
BitLocker Is Different
BitLocker or Device Encryption protects a drive, not a portable ZIP archive with its own password. Drive encryption is valuable if a PC or drive is lost, while archive encryption is useful when specific files need protection during storage or transfer.
Summary
Windows 10 cannot natively create a password-protected ZIP archive through File Explorer. Use a trusted archive tool with strong encryption, choose a unique password, verify the archive before deleting any originals, and keep the password secure. Prefer AES-based encryption when compatibility permits.
