Can't Encrypting Folder

Hi Jeanette,

The Encrypting File System (EFS) is the built-in encryption tool in Windows used to encrypt files and folders on NTFS drives to protect them from unwanted access. This is the strongest protection that is available in Windows to help you
keep your individual files and folders secure. Here are the steps on how you can encrypt files and folders in Windows 10:

• Right-click the folder or file you want to encrypt, and then click Properties.
• In the General tab, click on the Advanced button.
• Check the Encrypt contents to secure data box, and click on OK.
• Click OK and close Properties window.
• Apply changes to the folder, subfolders and files when prompted. If it is a file, select to either Encrypt the file and its parent folder or Encrypt the file only for what you want, and click
  on OK.

Tip: The first time you encrypt a folder or file, an encryption certificate is automatically created. You should backup your encryption certificate. If you lose access to your encrypted files
and folders, you will not be able to open them again unless you first restore the file encryption key for them.
