How to password protect a 7-Zip file in Windows 10?

You can password protect a 7-zip file the command line options in Windows 10 or Windows 11. The ​​7zexecutable​​ refers to the command-line version of the ​​7-Zip​​ archiving tool. It is a standalone program that allows you to create, extract, and manage compressed archives (like .7z, .zip, etc.) directly from a terminal or command prompt, without needing to open the graphical user interface.

Once you know where 7zis located (or it's in your PATH), you can run commands like:

7z a -p MyPassword archive.7z myfile.txt

This creates a password-protected .7zarchive named archive.7zcontaining myfile.txt.

If you're unsure whether 7zis installed or available on your system, you can try running in your terminal or command prompt. If it's not found, you'll need to download and install 7-Zip.:

7z

After adding password to 7-zip file in Windows 10, you can verify the encryption with this command:

7z x archive.7z -p mypassword
