Why Are My Files Green In Windows 7?

As you explore your files and folders in Windows 7, you may notice some have a green tint. Microsoft doesn’t just choose this hue for aesthetic reasons; there is actually an important reason behind its appearance that might surprise you. In this article we will explain what this signifies.

What Does Green Mean in Windows 7?

A Brief Explanation Windows 7’s green color serves as a visual indicator that an encrypted file or folder has been protected with Encrypting File System (EFS).

What Is EFS (Encrypting File System)

Windows offers the Encrypting File System (EFS), a feature which enables users to encrypt files and folders using EFS encryption technology. When data in a file or folder is encrypted by EFS encryption technology, its data becomes indecipherable until decoded with your private key; making it more difficult for unauthorised individuals to gain access to sensitive information stored within it.

Why Are My Files Encrypted With EFS?

In certain circumstances, Windows 7 may automatically encrypt files and folders for you. For instance, when creating new user accounts on your computer, Windows will encrypt their folder with EFS encryption by default.

Manual Encryption EFS allows for manual encryption of files and folders as well. To do this, right-clicking the desired file or folder you’d like to secure then right-clicking “Properties,” selecting “Advanced,” selecting “Encrypt Contents to Secure Data,” and finally “OK” can encrypt everything within.

What Are the Consequences of Losing an EFS Key? In case of losing your EFS private key, any files or folders encrypted using it become inaccessible – creating major difficulties should you hold any important data within them.

Recovery Agents

Windows 7 allows users to reduce this risk by creating Recovery Agents – user accounts authorized to recover EFS-encrypted files and folders. You can create one following this Microsoft article’s instructions.


Windows 7’s green color serves more than just as an aesthetic choice, it also signals that files or folders encrypted using EFS are fortified against loss by providing another layer of security. Unfortunately, losing your EFS private key could result in you no longer accessing any encrypted files or folders; to safeguard against such situations it is wise to create recovery agents as backup.
