We do have data in our computer which are confidential and are to need to be kept secure and away from the access of all other’s using your computer. Simplest way to do so it to lock the folder with password and make it secure. So in this article we are going to discuss How to password protect a folder without using any third party software in Windows, MAC or Linux OS ? Or we can say in short how to Folder Lock without using any software.

There are mainly three OS running in the market they are Windows, MAC and Linux. Since all three are different each one has different methods to be adopted for folder lock.

Folder Locking in Windows OS without using any software to protect your confidential data :

Here we will be discussing methods to folder lock without using any software in windows. To do so follow below steps :

Step 1 : Copy the following code into the notepad.

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%==type your password here 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 2 : Replace the line “type your password here” with the password you wish to keep for the folder.

Step 3 : Rename the notepad into some unique names like system 32, system file, etc. Also change the extension to .bat from .txt so that the file may look like system file and no one will touch it.

Step 4 : Now place the file (.bat) which you created in last step into the folder where the confidential data which is to be locked is present. Click on the .bat file to run it.

Step 5 : Doing the last step will make out a folder named “locker” now copy all data and place it into that folder. Click on the .bat file once again and the folder will get hidden and data in it will be password protected along with the folder lock.

Note: You can change the folder name from “locker” to whatever you wish just replace word locker from that .bat file with name you wish to give to the folder.

Step 6 : Now your data is safe, password protected and hidden in the locker folder. To get back the data click on the .bat file once again and you will be prompted with a command prompt enter the password and the locker folder will be unhided and can be accessed.

This way you can secure your data in windows by folder locking your data and without using any software. But do take in mind this method is not completely secure. So use it only when your data is not so much confidential.

Folder Locking in MAC OS without using any software to protect your confidential data :

Here you will find methods to folder lock files in MAC OS without using any software. To do so follow below steps :

Step 1 : Open “Disk Utility” in your Computer.

Step 2 : Go to “File” then click on “New” then click on “Disk Image from Folder”.

Step 3 : Choose the folder here which you wish to password protect.

Step 4 : Choose “AES-128″ folder encryption and then click on Save.

This way you will be able to password protect your files in MAC OS without using any software.

Folder Locking in Linux OS without using any software to protect your confidential data :

To secure your files in Linux all you need to do is move the files to a single folder and check out the read permissions for other and group are not set to access it. And then follow below steps :

Step 1 : To do all you need to do is create a folder and move the files to be secured into it.

Step 2 : Open terminal and type the following command :

chmod -R go-rx FOLDER NAME

Replace “FOLDER NAME” with your folder name. This will set security level to read, write and execute for you and for all others it will get secure. No one else except you can’t access this file now. Do take care that still root user can access your folder. So in Linux to password protect your folder you need to use compression software.
