Lock a folder without any additional software

Do you want to protect your personal files but hate installing a totally new software for it.
YES, it can be done without any software.

Difficulty level: VERY EASY

Step 1.>
Go to the location where you want to create a Locker.

Step 2.>
Create a new notepad file and copy the below code exactly as it is:-

cls
@ECHO OFF
title Folder Locker
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Locker goto MDLOCKER
:CONFIRM
echo Are you sure u want to Lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder
set/p "pass=>"
if NOT %pass%==nikoo28 goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Locker
echo Locker created successfully
goto End
:End

Step 3.>
Look for the text "nikoo28" in the above code. This was the password for my folder locker. You can change it as per your requirement. Just remove it and type your own.

Step 4.>
Save this file by the name of locker and change its extension to .bat

Step 5.>
You are almost done now. Just double click the file. If this is the first time you are using this locker.bat file, a folder named Locker will automatically be created.

Now drag all your personal files in this folder.

Once you are done, again double click the locker.bat file and you will be asked for a confirmation dialog "DO YOU WANT TO LOCK? (Y/N)". Press Y and your folder will be locked.

To Unlock, double click the locker.bat file again and you will be prompted for a password. Enter it and your folder will reappear... :-D

I hope this tutorial helps....any further discussion can be done in the comments.

Send encrypted emails (private emails)

Sending private email messages is one thing and sending encrypted email messages is another.
For naive users encryption can be very tough. I recently found this web tool that allows you to easily encrypt your messages and send it as a email.
Encryption is basically a technique to protect your messages even if your account is hacked. They can only be decoded if you have the correct key to decrypt the messages.

So, if you need to send some really confidential messages I propose to you a very easy solution.

Step 1.>
Open www.lockbin.com

Step 2.>
This site offers a free encryption facility. Click on 'Start Now'.

Step 3.>
You are now presented with a form, in which you can fill the particulars, enter a secret password and then send the email to the desired recipients. After filling the form click on submit to send the email.

Step 4.>
Now, you need to convey the secret key to the receiver through some means like a text message or a phone call. This is a secure method as you can set the same password every time you send an encrypted mail.

That's it...you are done.
This method of encryption is an added layer of security to protect your confidential messages. Go ahead and give it a try...

Make your laptop a wifi hotspot

Most of us have seen the feature in android phones which allows you to convert your phone into a wifi hotspot and then the mobile's data connection can be used in latops or other wifi devices to connect to the Internet.

Have you ever wondered if you could do the same with your laptop.
Suppose you have a USB modem(or a LAN connection) that allows you to connect to the Internet on your Laptop but you are limited and cannot use that Internet connection on your mobile device or some other laptop.

Maybe you are in a room with 3 or more friends where one of the guys has a USB modem. Only 1 person can access the internet at a time?? If you have any of these problems, I present you a solution which will help you out... : D

You can convert your laptop into a wifi hotspot using a third party tool 'mhotspot'. Download Link.

Step 1.> Download the above software. Its a very small 300Kb file. ;-)

Step 2.> Run the downloaded file.Goto Setup tab and enter the hotspot name and password of your choice.

Step 3.> Now,goto hotspot tab , click Start hotspot and "open network and sharing centre".

Step 4.> Click on the blue label of your active internet connection . 

Example:- Local area connection,PPOE connection, 3G-USB Connection, etc.

Step 5.> Then a status box will appear, click properies.

Step 6.> Go to sharing tab and tick the box,"Allow other users to connect through this computer's internet connection" and select the wireless network connection 2(This is the same name which appeared in the image of step 4). 

Step 7.> Click "start hotspot" to enable sharing your internet through wifi.

Step 8.> Final view.

  

And you are done.... !!  

Now you can view and connect to this network on your other wifi devices and use it freely... :D
 You need not configure this entire process every time you set up a hotspot. One time configuration will do.

If you change your internet connection, then you need to reconfigure.

You can even create a hotspot if you are accessing internet using a LAN cable also.
