Lock the file without using any software

You also can create file locker easly
Try this one

Steps:

1- make a new folder ( name it as you like )
2- inside this folder make a (.TXT ) file & copy the the following code given below

CODEQuote: cls
@ECHO OFF
title Folder Private
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you 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 Private "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%== hacker goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:End

3- now your password is hacker
4- After that, save it as locker.bat (the txt file will change to an application file)
5- Now go back to the folder & u will find a this locker.bat file.
6- Click on it & u will find a new folder called Private.
7- Now copy what u want in it & after that go to locker.bat by clicking it, it will open and ask you if you want to lock your folder? Y/N ?
8- Type Y
9- If you want to UNLOCK your folder, go open locker.bat & type your password and the Private folder will be made visible again.
10-if you want to change password go to line ( 23 ) u will find "hacker" Change to any password u want.

That's all now you created a file locker
(if you wnt to convert you locker.bat to locker.exe download this and convert.)
