I. What is Controlled Folder Access on Windows 11?

Controlled Folder Access on Windows 11 is a security feature built into Windows Security (formerly Windows Defender) that protects important files and folders from malware, especially ransomware. When this feature is enabled, only whitelisted applications can edit, change, or access files in protected folders.

How Controlled Folder Access Works :

1. Block unauthorized access : Allow only trusted applications (Microsoft-certified or user-specified) to access protected folders.
2. Prevent Ransomware : Ransomware often attempts to encrypt users' files. Controlled Folder Access prevents this by blocking access to untrusted applications.
3. User warning : If an unauthorized application tries to access the folder, Windows sends a warning message.

Advantages of Controlled Folder Access :

1. Protect important data from malware or ransomware.
2. Easy to customize: Users can add apps or folders as needed.
3. Built into Windows 11 for free, no third-party software required.

Disadvantages of Controlled Folder Access :

1. It can be inconvenient that unverified apps will be blocked from accessing folders, even if they are safe.
2. Requires users to manually add apps that are not in the trusted list.
