• Password Protection for Folders. Allows you to assign passwords to any folder on the system. Files inside the protected folder are not accessible without the correct password. You can use individual passwords for different folders or a master password to manage them all.
• Hiding Folders and Files. Makes specific folders and files invisible to the operating system and most applications. Hidden items do not appear in Windows Explorer, in open/save dialogs, or in command-line utilities.
• Restricting Access to the Control Panel. Blocks full or partial access to the Windows Control Panel. This function prevents unauthorized users from modifying critical system settings, such as network settings, user accounts, or security options.
• Blocking Removable Drives. Controls access to USB drives, external hard disks, CD/DVDs, and other removable media. It can completely disable writing to or reading from these drives to prevent unauthorized data copying or the execution of external software.
• User Profile Configuration. Allows you to create and apply different sets of protection rules depending on the user logged into Windows. Restrictions and permissions are activated automatically based on the account.
• Stealth Mode. Hides the Folder Guard installation itself, its shortcuts, and program files. This mode prevents advanced users from detecting, uninstalling, or modifying the security software's settings.
• Access via Hot Key. Offers the ability to enable or disable all protection with a specific key combination. This action is also password-protected to prevent unauthorized use.
• Designation of Trusted Programs. Allows you to specify applications (such as antivirus, backup, or maintenance software) that are permitted to access protected files and folders without prompting for a password, enabling automated operations.
• Advanced Filters by File Type. Enables the application of rules based on file extensions. For example, you can block the modification of all executable files (.exe, .dll) while allowing full access to documents (.docx, .xlsx).
• File System Independent Protection. Works on volumes formatted with FAT32, exFAT, and NTFS. The protection is applied at the operating system level and does not depend on the native security capabilities of the file system.
• Emergency Recovery Utility. Includes an external tool to recover access to protected data in case the main password is forgotten or a system failure occurs. This utility requires a specific procedure for its use.
• Administration Kit for Businesses. Offers special versions (MSI/EXE) and Group Policy templates for centralized deployment and management in corporate environments. It allows distributing licenses and configurations to multiple computers on a network.
• Integrated Advisor and Assistant. The software incorporates a wizard to guide you through the initial setup and an advisor that alerts you to potentially problematic configurations, such as attempting to protect critical operating system folders.

Folder Guard was initially developed by WinAbility® Software Corporation. Its first commercial version was released in 1997. The program has been maintained and updated continuously since then, with adaptations for each new version of Windows, from Windows 2000 to Windows 11. The software is written primarily in the C++ programming language.
