PC users often use 7-Zip to extract files downloaded from the internet. In addition to unpacking files and creating ZIP or 7Z files, the 7-Zip software can also be used to encrypt files and folders using the strong AES-256 encryption.
7-Zip supports AES-256 encryption in 7z and ZIP formats, allowing you to create password protected zip or 7z files using the AES-256 encryption method.
If you want to password protect your data without using any expensive software, you can use 7-Zip to encrypt files and folders in Windows 10. For instance, you can encrypt all files and folders on your USB drive quickly.
When you use 7-Zip to encrypt your data, 7-Zip creates a ZIP or 7Z file containing your valuable data. To open the files in the encrypted ZIP or 7Z file, you will have to enter the password.
