How to set a password for a folder without any software

There is no function to set a password, but it can encrypt files (folders), and encrypted files (folders) must meet 2 conditions:

1. File system NTFS format.

2. There must be 2 or more users (although one user can encrypt, it does not have a good effect, mainly because the encryption decrypts the encrypted account by default).

It's okay to meet the above 2 conditions. The operation method is very simple, right-click on the folder - Properties - Advanced - select the encrypted content in order to protect the data - OK - OK - OK.

Explanation: After this method is encrypted, it can only be visible when the encrypted user logs in, and Windows 2000 can be seen after encryption with this method, and the encrypted content can be seen with the super administrator account; After XP (inclusive) or later encryption, other users (including super administrators) cannot view the encrypted content, although you can authorize other users to view the encrypted content. Note that after encryption with this method, be sure to restore the encrypted content when you reinstall the system, otherwise the encrypted content will not be restored.

No, if your hard drive is in NTFS format, you can set access rights at most!

Is it okay to use software? Can't you? Do you want others to see it? Just hide the files! Just remember the file name! Feel free to open it yourself!

Modifying the registry allows you to hide files or folders with the "Hide" attribute (even if you set Show left and right files in the folder options, you can't see them), and the built-in search of Windows can't find them.

For example, use the system's built-in EFS encryption.

Right-click on the folder and select Properties, click the Advanced button in the General tab, and select Encrypt Content to Protect Data.

Note: One of the most important steps after encryption is to back up the encryption certificate and private key.

Because, after using EFS encryption, only the current system account can access the system normally after logging in to the system, and the non-current account cannot access these encrypted files. When the system is reinstalled, even if you set the same account name, it is recognized as a non-encrypted system account, so you will not be able to access these encrypted files. In order to prevent the encrypted file from being opened, you need to back up the certificate and private key corresponding to the encrypted system account.

If you feel that this kind of encryption is a bit troublesome, you can also try to use encryption software for encryption, such as the folder encryption function of the folder encryption supermaster.

You can put it in the compressed package and add a password.
