lock folder with password without any software on windows

There are a few methods to lock a folder on Windows without using any software. Here are a few methods:

Method 1: Password-protect the folder using a batch file

1. Open Notepad.
2. Copy and paste the following code into Notepad:

   @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 you want to lock this folder? (Y/N)
   set/p "choice=>"
   if %choice%==Y goto LOCK
   if %choice%==y goto LOCK
   if %choice%==n goto END
   if %choice%==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%==yourpasswordhere 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
   

3. Replace "yourpasswordhere" in the code with your desired password.
4. Save the file with a .bat extension, such as "folderlock.bat".
5. Double-click the batch file to run it.
6. Type "Y" and press Enter to lock the folder.
7. The folder will now be hidden and inaccessible without the password. To unlock the folder, run the batch file again, type the password, and press Enter.

Method 2: Hide the folder using the attrib command

1. Open Command Prompt by typing "cmd" in the search bar and selecting "Command Prompt" from the results.
2. Navigate to the directory containing the folder you want to hide by using the "cd" command.
3. Type "attrib +h +s [folder name]" without the quotes, replacing "[folder name]" with the actual name of the folder.
4. Press Enter to execute the command.
5. The folder will now be hidden and inaccessible without the password. To unhide the folder, repeat the steps but replace the "+" with a "-" in the command.
