This page aims to expand what we set out to do with the first one and deliver even more in-depth and targeted information on how to protect files with a password. That page offered extensive information and even precise step-by-step guides on how to encrypt a password file for maximum security. In one of our earlier pages, we discussed how to password-protect a file or folder. Your password is the last line of defense between your data and those from whom you want to keep it private. Of course, they would not be able to open any of the files without the password.Protecting your files is crucial, as you can never be too safe when safeguarding valuable data from unwanted intruders. If the file names provide sensitive information, a thief could take advantage of that. One more problem with encrypted ZIP files: No matter which form of encryption you use, anyone with access to the files can see the name of the files within the archive. You’ll find these options near the lower-right corner of the dialog box. To encrypt an archive in 7-zip, once you’re at the Add to Archive dialog box, enter a password and select the Encryption method AES-256.

Email someone an AES-encrypted file, text them the password (safer than emailing it), and if they try to open it in Windows Explorer or File Explorer, they won’t be able to open any of the files within the archive.įortunately, most third-party zip tools, including the free 7-zip, support AES-256. Assuming you use a strong password, it’s for all practical purposes unbreakable.īut when you use it for ZIP archives, AES-256 comes with another problem: Windows’ own, built-in compression tool doesn’t support AES. It’s a popular and extremely strong encryption technique used in many programs. Unlike ZipCrypto, AES was not designed for ZIP files. You’d be far safer using the other option, AES-256.
