Vcoderz Community - Simple Folder Locker

This thread is for educational purposes.
Inspired from this thread:

I decided to make a simple folder protector for flash memory.
This is not extremely secured, it depends on who's running your flash memory (kevin mitnick or osama bin laden :p)
Note that this does not work on Windows Vista.

First:
This is a final demo release of the software version 1.0:

The password of this demo is "linux".

Second:
How this demo was made?
This is the raw program (source code):

Code:

@echo off color 0a for %%x in (%1) do set path=%%~dpx cd %path% cls echo Simple Folder Locker By Edgard Chammas. echo --------------------------------------- echo. :CHOICE ECHO Enter "l" To Lock Or "u" To Unlock Or "x" To Exit: set /p CH= if %CH%==l ( goto lock ) else if %CH%==u ( goto unlock ) else if %CH%==x ( goto bye ) else ( goto CHOICE ) :lock IF NOT EXIST secured goto FNE1 ren secured secured.{21EC2020-3AEA-1069-A2DD-08002B30309D} echo The Folder "secured" Is Now Locked! goto bye :unlock Echo Enter The Password In Order To Unlock The Folder "secured": set /p password= if %password%==linux ( IF NOT EXIST secured.{21EC2020-3AEA-1069-A2DD-08002B30309D} goto FNE2 ren secured.{21EC2020-3AEA-1069-A2DD-08002B30309D} secured echo The Folder "secured" Was Unlocked Successfully! goto bye ) else ( goto WP ) :WP echo You Entered A Wrong Password! echo Cannot Unlock The Folder! goto bye :FNE1 echo The Folder "secured" Does Not Exists Or It Is Locked! goto bye :FNE2 ECHO The Folder "secured" Does Not Exists Or It Is Not Locked! :bye pause

This code is saved as "locker.bat"
The batch file is converted to an executable file using "Quick Batch File Compiler"
The executable file is packed using UPX 3.1
