Using encrypted archives with 7-Zip
1. Creating an archive
- From any Windows Explorer window (e.g. My Documents), right-click on the file or folder you want to encrypt. Select 7-Zip and then Add to archive .
- Select the Archive format . 7z offers better compression (makes the files smaller) but .zip is usually a better choice because it offers better compatibility with other programs, such as WinZip. In the Encryption section, enter a strong password and select AES-256 as the encryption method.
Extracting files from an archive
- To extract the files, right click on the archive, and click Extract files .
- In the window that appears, you select where to extract the files to and enter the password for the archive. After clicking OK the files will be unencrypted and extracted to the location you specified.
