• Mass folder locking. Allows selecting multiple directories and applying protection simultaneously. The function processes all items in a single operation, reducing the time required to configure security in complex file structures.
• Password protection. Implements an authentication system based on alphanumeric keys. Each locked folder requires entering the correct credential to allow access to its contents.
• Directory hiding. Modifies system attributes to make protected folders invisible in File Explorer. This additional layer prevents casual detection of sensitive data.
• Permission restriction. Limits available actions for unauthorized users, including reading, writing, modifying, and deleting files within locked folders.
• Command line interface. Offers compatibility with execution via CLI parameters for integration into scripts and automation of repetitive tasks without graphical interaction.
• Activity logging. Generates detailed log files with information about access attempts, password changes, and modifications to protection status.
• Portability. Requires no permanent installation, allowing execution from external devices such as USB drives without leaving traces on the host system.
• Customizable security levels. Allows adjusting individual protection parameters for each folder, including different passwords and locking methods according to specific needs.
• Network compatibility. Works with directories located on mapped drives and network shared resources, maintaining protection in corporate environments.
• Emergency recovery. Includes a mechanism to reset lost passwords using preconfigured security questions, preventing permanent loss of access.
• Shell integration. Adds context menu options in Windows Explorer's right-click menu to lock/unlock folders directly from their location.
• Process exclusion. Allows defining authorized applications that can access locked contents without requiring authentication, useful for automated backups.

BulkFolderLocker was developed by AutoClose Software, specialists in productivity and security tools. The first version was released in 2018 as a complementary utility for system administrators. The code is written in C++ with .NET Framework components for the graphical interface. Regular updates incorporate improvements to the encryption algorithm and compatibility with new versions of Windows.
