If the "Encrypt contents to secure data" option is not selectable or available, you likely have a Home edition of Windows, which does not support this feature. It is also possible that the hard drive where the files are located is not formatted as NTFS, which is required.
Users can still view a list of the files within a compressed file. If you want both your file names and contents to be hidden, move all the files into a single folder and password protect that folder.
how to lock a zip file windows 7
So I am trying to figure out how to password protect a zip file using the built in zipping utility in windows 7. In windows xp and vista once you have created a zipped file you open the file and select file>add password.
In windows 7 (currently using pro) there is no "add password" option, anyone have any idea why this is? Or is there some other way of adding a password to a windows zip file that I am not aware of? Am I being forced to add a 3rd party zip app in order to password protect files?
No, you can't use a password to protect files and folders inWindows. However, some programs that run on Windows allow you to protect individual files with a password. For more information, check the Help for the program you're using.
There are other ways to protect your files and folders in Windows. You canencrypt your files using Encrypting File System (EFS), manually specify who can access the folders or files by setting permissions, or hide them. Choose your method based on how secure the folders or files need to be. Encrypting is the most secure, while hiding the folders is the least secure.
I too just now learned the hard way that Windows 7 cannot extract password-encrypted ZIP files I created with WinZip, when I sent one to a Windows 7 user. So: WinZip can create and extract password-protected ZIP files, and it runs under Windows. You can download it from
Note:7-Zip uses password-based encryption, and even a strong encryption algorithm like AES is of little or no benefit if the passwords you use are weak, or you do not keep track of them in a secure manner.
In particular, encrypted files can be deleted from a Zip file, or renamed within a Zip file while new, unencrypted files can be added to a Zip file without a password.
For details on AES encryption method, please refer to _Encryption_Standard from Wikipedia.
Zipped (compressed) files take up less storage space and can be transferred to other computers more quickly than uncompressed files. In Windows, you work with zipped files and folders in the same way that you work with uncompressed files and folders. Combine several files into a single zipped folder to more easily share a group of files.
Press and hold (or right-click) the file or folder, select (or point to) Send to, and then select Compressed (zipped) folder.A new zipped folder with the same name is created in the same location. To rename it, press and hold (or right-click) the folder, select Rename, and then type the new name.
If you add encrypted files to a zipped folder, they'll be unencrypted when they're unzipped, which might result in unintentional disclosure of personal or sensitive information. For that reason, we recommend that you avoid zipping encrypted files.
Some types of files, like JPEG images, are already highly compressed. If you zip several JPEG pictures into a folder, the total size of the folder will be about the same as the original collection of pictures.
Zip archive has become popular since it can save computer space and is convenient to transfer. However, some users still don't know how to password protect a Zip file from unauthorized access. In order to achieve that, we need to take advantage of some third-party programs. In this article, we'll share 3 methods with you. What's important, we'll also tell you how to access an encrypted Zip file if you forgot the password.
WinZip is a popular and professional compressor for Windows 7/8/8.1/10. It can create archives in .zip and .zipx file format. When you create a .zip or .zipx file, you have the option to encrypt the file. It supports 128-bit and 256-bit key AES encryption, which are now used worldwide. Now, let's check how to add a password to a Zip file with WinZip.
7-Zip is a free file archiver. It has its own archive format with .7z file extension, but it still supports to create a compressed file in other archive formats like bzip2, gzip, tar, wim, xz and zip. If you'd like to put a password on a Zip file with 7-Zip, you have 2 encryption methods including AES-256 and ZipCrypto. The former offers stronger encryption, and is now supported by many common-used archivers.

WinRAR is a trialware file archiver for Windows XP and later. It can create and access compressed files in RAR and Zip format. According to some official statements, it supports AES encryption. However, when you set a password for the Zip file, you only have the "Zip legacy encryption" option. This is an older encryption technique, and it's known to be relatively weak. You shouldn't rely on it to provide strong security for your data.
Now that you have added a password to your Zip file, there is a possibility that you may forget the password of it. What will you do at that time? I bet you will try to enter all possible passwords and you may end up not being successful. In such a scenario you also need to rely on a third-party program that has the ability to unlock Zip files without knowing the password.
A program that allows you to unlock encrypted Zip files is Passper for ZIP. It is a powerful password recovery tool that allows to retrieve passwords from Zip files created by WinZip/7-Zip/PKZIP/WinRAR. The program is equipped with 4 smart recovery methods that will greatly reduce the candidate passwords and then shorten the recovery time.

It doesn't require an Internet connection during the recovery process, therefore, your file won't be uploaded to its server. Thus, your data privacy is 100% secured.
Without further ado, let us now take you through on how to unlock the encrypted Zip files with Passper for ZIP.To begin with, you need to install Passper for ZIP on your computer. Therefore, download the Windows version and install it on your computer.
Step 3Once selected the attack mode, click on the "Recover" button, then the program will start to recover your password immediately. Once the password is recovered, the program will notify you that the password has been recovered. From there, you can copy the password to access your password protected Zip file.
Luckily, there are plenty of free tools out there to create a password protected zip file. In this guide, we will show you how you can use two popular tools WinRAR and 7-Zip (free) to create a zip file with password.
Step 2: Now that 7-Zip is installed, right-click on the file that you would to create an archive and add password protection, click 7-Zip, and then click Add to archive option. This will open Add to archive dialog.
Step 4: In order to protect it with a password, move to the Encryption section, enter a password, re-enter the same, and finally, click OK button. This zip file will appear in the same folder where your original file is located.
Step 3: Here, Enter a name for your archive (password protected file in this case), and select ZIP as archive format. Be sure to select ZIP as archive format as WinRAR uses its .RAR as archive format with default settings.
I used .zip file protection under XP and have found with Win 8.1 the protocol for opening with a password has changed. Under XP, after I closed an archive, I would have to reenter the password if I needed to reopen it. Now it seems as long as I have opened it once, it remains accessible without re-entering the password until I log out/in again . I would prefer to have the protection resume after closing the archive. Can I change a setting somewhere to do this?
Using a password to protect a folder means that you need to enter a password to see the list of documents in the folder. You can also password-protect individual files either in a password-protected folder or in a folder without password protection. The procedure is the same for files and folders.
Password-protecting a zipped file is a good solution if your version of Windows does not support password protection. If you put the files you'd like to protect in a zip file, you can then apply a password.
Although Microsoft has taken away the ability to password-protect a folder, you can still keep your confidential information private by using either a password-protected zipped folder or hiding files and folders so they don't appear in the directory list.
The 7Zip is one of the best archiving and compression tools in its field. It is even better than similar compression tools that are popular for some basic consumers. Also, 7Zip is not just about creating and extracting ZIP and RAR files. It supports the most number of compression formats that exist today. 2ff7e9595c
