    Tips to Open Password-Protected ZIP Files

    You may know how to create a ZIP file on windows or on Mac. But when you get your hands on a password-protected ZIP file, you may be not sure how to open it. Maybe you downloaded it from the internet, or a colleague sent it to you via email. Whatever the case, if you want to learn how to open it up and access the files within, you’re in the right place!

    How ZIP Files Work

    You’ve almost certainly come across a ZIP file or two, but you might never have considered how they work. Well, ZIP files use ZIP — the most widely used archive file format — to compress files and reduce the storage space they take up. There’s nothing complicated about it — a ZIP file is nothing more than a file containing one or more compressed files.

    ZIP files work great when you need to send someone a collection of files because you can compress them all together. They work especially well when sending files via email because you don’t need to attach every file individually, and the reduced size of the ZIP file makes it so you can send more/larger files before reaching the attachment size limit.

    How to Open Encrypted ZIP Files

    OK, so ZIP files are great for convenience and saving on storage space, but how exactly do you open them, especially when they’re encrypted? If you know the password to an encrypted ZIP file, opening it, or “unzipping” it, is easy.

    Both Windows and Mac come with built-in support for creating and opening ZIP files. So you may know how to create or open a zip file on windows or on Mac. Unfortunately, though, this support can be described as basic at best. However, there are many free apps available that come highly recommend that offer lots of other additional, useful features. Perhaps the best of them all is Unarchiver One.

    How to Open Password-Protected ZIP Files Without a Password

    But what about opening Password-Protected ZIP files when you don’t have the password? Well, that’s where things become a little tricky.

    Apps that can open Password-Protected ZIP files without the need for a password do exist, but their legitimacy and safety are questionable. Decrypting files with complex encryption is not an easy task, so any apps that claim to do it — especially ones that are available for free or very cheap — are likely to be malicious. It is for this reason that we do not recommend using such apps. Instead, we would recommend trying all you can to obtain the password.

    If you downloaded the file online, the uploader almost certainly posted the password too. If your colleague sent the file to you but forgot to give you the password, it’s best to ask them for it. It is much better to obtain the password than use potentially dangerous apps.
