![]() It scrambles or, rather, ciphers the data within the file, turning it to an unreadable ciphertext. This script looks for the 7zip executable (7z.exe) in the default install locations, and if not found it will use the stand-alone 7zip executable (7za.exe) if it is in the same directory as the powershell script. file a.txt is encrypted with "p4sSword1", file b.txt is encrypted with "Passw0rd2", file c.txt is not encrypted) so if you decide to use this (format's) feature you can need to enter different passwords to operate on (extract, update) different files inside the same archive - so the concept of asking for "the" password when you open an encrypted archive may be deceptive as that password may apply only to part of the archive's content. The process of protecting files is called file encryption. Here is the function I wrote that uses 7zip to perform the zip, since 7zip supports using a password to zip the files. The issue is utterly complicated as both Zip and 7z format support different passwords being used in the same archive (e.g. ![]() ![]() with a plain hex viewer), so the archive format does not offer any security at all if attacker's scope is just reading the file names.ħz format can optionally encrypt archive's table of content, in this way you will always need to enter the password to browse the content.īoth with Zip and 7z formats, however, you cannot extract anything from an encrypted archive without providing the password, as the file content is actually encrypted. Some archive managers can check if the file is encrypted and, in this case, ask you for password, but anyway the names of files and folders inside the encrypted Zip archive are in clear text and anyone can read them (e.g. Download and install the 7-Zip program following the installation steps. ![]() For most users, this is the 圆4 Windows build that runs on the majority of modern Windows computers. Go to the 7-Zip website and pick the appropriate version for your PC. Zip format does not allow to encrypt table of content of the archive, so you can actually open (browse) any encrypted Zip file. Having said that, here’s how to password protect a folder in Windows 10 with 7-Zip: Step 1.
