Password Protect Files, Folders, USB Drives, and Shared Folders on Windows

GiliSoft File Lock Pro is a Windows folder lock and file protection tool built for people who need stronger privacy controls than standard file permissions. Use it to lock folders with a password, hide sensitive files, protect data on USB drives, restrict changes with read-only mode, and secure shared folders on a local network.
It is designed for personal documents, office folders, portable drives, and small-team environments where you need quick access control without a complex deployment. In one application, you can lock, hide, encrypt, monitor, and securely shred files so private data stays protected from unauthorized viewing, editing, copying, or recovery.

Who Is This For?

People who share a Windows PC and need stronger folder privacy

Use File Lock Pro when sensitive folders should stay private from family members, coworkers, students, or other users on the same computer.

Small teams that use USB drives and shared folders every day

It works well for office documents, HR files, project folders, and portable files that move between workstations, external drives, and LAN shared folders.

Users who want faster access control than full-disk security tools

If you do not need to encrypt an entire system drive, File Lock Pro gives you focused file and folder protection with quicker setup and more granular control.

Why Not Just Use Windows Permissions, BitLocker, or EFS?

Windows permissions are useful, but not always simple for personal privacy

NTFS permissions can work well for managed systems, but they are often inconvenient for home users or small teams that want quick password-based protection on specific folders.

BitLocker is great for full-drive security, not always for folder-level control

BitLocker protects an entire drive. File Lock Pro is better when your main task is locking or hiding selected files and folders, controlling USB folder access, or protecting a LAN shared folder without changing the whole drive workflow.

EFS is built into Windows, but it does not cover the same practical use cases

EFS focuses on file encryption tied to user accounts. File Lock Pro combines folder locking, hide mode, read-only protection, monitoring, shared-folder control, portable encryption, and secure deletion in one place.

Core File Protection Features

Hiding Files/Folders/Drives

Hide your private files/folders from local disk or external (USB) disk, completely invisible to anyone or any programs even under Windows Safe Mode. Make your private data unsearchable. All hidden files are never shown in search results.

Folder/Disk Monitoring

Monitor a disk or a folder and its sub-folders when changing and writing or any operations or changes make by a user.

Locking LAN Shared Folder

Permanently delete files and folders, ensuring they cannot be recovered from the recycle bin or by data recovery tools, preventing unauthorized retrieval.
