In this article, we have explained two solutions on how to encrypt a folder in Windows 10 in order to protect your files on Windows 10. So. continue reading to encrypt a file using folder encryption software.

How to Encrypt a Folder in Windows 10

Depending on what you are looking to encrypt, there are different folder encryption software that can be used. Windows 10 offers two built-in tools for this purpose, namely, EFS and Bitlocker. EFS stands for Encrypting File System and is used to encrypt individual files and folders whereas Bitlocker is used to encrypt entire volumes. Apart from these native tools, there are also a plethora of third-party encryption applications available on the internet which offer additional features.

Method 1: Use Encrypting File System on Windows Enterprise & Pro

More often than not, users are only looking to protect certain files from their privacy-invading siblings or envious colleagues who have access to their computer. If that is indeed the case, making separate user accounts is the first step followed by denying access to your personal files to other users. This can be achieved by using the EFS feature which encrypts data on NTFS drives on a per-user basis.

  • In layman’s terms, only the user account that encrypted the files will be able to access them. And, all other accounts will be prohibited from interacting with the encrypted file.
  • You simply need to log in from that user account to access the files and need not enter the encryption password again.
  • Although, be sure to set a strong password for your user account as that is the only thing that stands between others accessing your encrypted files and folders.

Note: EFS is only available on Enterprise and Professional versions of Windows.

Follow the steps listed below to encrypt a folder in Windows 10 using EFS.
