How to Encrypt and Decrypt Files and Folders in Windows 10

Windows includes an advanced security feature called Encrypting File System (EFS). It allows users to store encrypted files and folders to protect them from unnecessary access. Other user accounts cannot access your encrypted files. This is the strongest protection in Windows that can be used to protect individual files and folders without encrypting the entire drive.

• Part 2: Encrypt / decrypt files and folders in Command Prompt
• Part 3: Encrypt / decrypt files and folders in iSumsoft FileCarer

How to Encrypt / Decrypt Files and Folders using Advanced Properties

1. Right-click on the file or folder, and select Properties from the context menu.

2. In the Properties dialog, click the Advanced button on the General tab.

Step 3: Click to check the option Encrypt contents to secure data.

Decrypt files and folders: Clear the Encrypt contents to secure data check box, and then click OK.

When the first you encrypt a file or folder, you may be prompted to back up the file encryption key to helping avoid permanently losing access to encrypted data. Encryption will be disabled for a folder, if you compress the folder, move it to a ZIP archive, or copy to a location that does not support NTFS encryption with EFS.

How to Encypt / Decrypt Files and Folders using Cipher Command

Step 1: Press Win+X, hit A to open Command Prompt (Admin).

Step 2: Execute one of the following commands as needed.

To encrypt a file or foler, type in the following command, then hit Enter.

cipher /e "PATH" (Replace PATH with the full address of the file / foler including the extension.)

To encrypt the folder and other files and folders inside it, you will have to use this command,

cipher /e/s:"PATH"

To decrypt a single file, run the command cipher /d "full path to the file".

To decrypt a folder, type the following command: cipher / d "full path to the folder".
