Depending on your settings, a system message "File Encryption System" may appear in the lower right corner of the desktop.

WARNINGtranslation text: Encryption in this way is linked to your account in the Windows 10 system. This means that another user of the same computer or network will not have access to the encrypted content, but when you are logged into the system (i.e., using your profile), entering a password is not necessary. It is worth remembering this, for example, when you want to password-protect a folder from children – to ensure no one has access to a given folder, you must first log out of your profile on the computer.

1. Click File → New Image → Image from Folder
   
2. The tool will then ask you to select the specific folder to be protected. You can choose a different name and location for the encrypted version (i.e., image) than the original.
   
   
   
   

3. Choose the type of AES (Advanced Encryption Standard) encryption – you can choose between 128-bit and 256-bit options. For typical "home" folder protection, it doesn't make much difference – the safer decryption in the 256-bit version may simply take a little longer.

   
   
   
   
4. In the tab below "Image format" select "Read and write". Then enter the password – the same in both fields. After clicking "save" and a short moment, the folder is secured.
