中文介绍

Usage Demonstration

On the folder you want to lock, right-click to call out the lock panel, and enter the password twice to confirm the lock.

On the locked folder, right-click, enter the password to cancel the lock.

Project Introduction

The project is divided into two directories:

  • DButility
    • Used to save passwords through the lightweight database SQLite.
    • The password is encrypted by Md5 algorithm, and SQL injection is prevented by SQL parameters.
  • folderLocker
    • Used to implement business logic.

Note before using it:

  • The password is saved in the local database and is not uploaded to any server.
  • Removing the software also deletes the database and therefore the password is gone.

How to use

  • Download the software package Folder Locker.exe
  • For installation, it is recommended to install it on the D drive.
  • You can use it by right-clicking, or by clicking the icon and open the software interface.

Trouble shooting

If you forget your password:

If the password is lost and the file is locked, it can be renamed via the command line tool.

For example, if your folder is E:\folder, open the cmd command window and execute the following command

ren e:\folder.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0} new_folder

Where {2559a1f2-21d7-11d4-bdaf-00c04f60b9f0} remains unchanged, and "new_folder" is replaced with the file name you want.

Note: In version 1.3.0, an universal password (Albert-W, i.e. my github id) can unlock all folders.
