Lock Folder/File with CMD | Protecting my Data | Locker 3.0

Locking and protecting my data is a really big issue in this digital era. And, I had already done a project in order to make it possible with some notepad tricks and hacks. The older version of this project, (The origin of this Idea) – LOCKER by KVC was also written in Batch.

And, most of you know that ‘Locker’ was my first batch application, which I have created for securing my private data. This Program is good to lock personal folders/files with the help of CMD. It was made around 2014.

LOCK A FOLDER/FILE USING CMD – My Story

This was that time – when I just started learning batch programming from unofficial websites and other sources. I came across a very simple and foolish Batch Program, named as ‘Locker’. The reason I said it was foolish was that the script itself contains the password. This is bad coding practice!

In other words, Anyone who knows what an IF statement does in any program can easily get the password. The program is comparing your entered data to a simple string built into the file. And once you know that string, you know the real password.

I decided to upgrade the Locker 1.0 project’s code since I have already told you that “It was my first Program”. It took me about 2 months to completely develop a locking programThe interface was although very weird and unpleasant, but I managed to complete my first self-started project. So, I named it ‘Locker v.2.0’.

The program saves the Username & Password to a different location, rather than hard-coding it and included everything in the Program’s script. Thus, it is a little safer than Locker v.1.0. [unless you know the location of the Password file]

LOCKER VERSION 3.0 BY KVC – In VB & Batch

Then after a few months, I thought to make this program more powerful and effective with a better data handling technique, And a better UI (user interface). So, I moved towards  Visual Basic, and I started working on it using Visual StudioAnd after a few months, I came up with the Locker Version 3.0 By Kvc{Hell of a lot of experiments I did at that time!}

As VB Provides pre-prepared UI for the programs, I didn’t need to make it from scratch. This version also uses some files of the previous version to accomplish its task. Although it is much stable and easy to understand than older versions of Locker.
