On any system, what a process can do only depends on the user id and not on the application. What you want would only be possible on a Unix-like where an application can run under a specific user thanks to the set user id feature. On Windows, the only possible way is to split the application :

a back end service running under a dedicated user that will own and edit the file
a front end application for user interaction that will communicate with the back end service. BTW this is now the best practices way, even on Unix like systems.

Steps to Lock and hide a folder.

) Put your file inside a folder.
) Get into that folder and create a new text file and name it anything.
) Copy paste the below code inside the text file:

    
    @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%==Enter-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

) Find for 'Enter-Your-Password-Here' inside the file and replace it with your password for the file.
) Click on file menu on the left most corner and click on 'Save As...'
) Add '.bat' extension to the filename. For ex : if the filename is locker.txt, then make it locker.bat.
) Click on save and save the file.
) Double click on the locker.bat file. A locker folder will appear.
) Place all the files to be locked in to that folder.
) Double click on the locker.bat file again.
) A command prompt will open. It will ask if you want to lock the folder.Type Y and press enter.
) Whenever you want to open the folder, double click on the locker.bat file again. Enter the password and press enter.
) The folder will reappear.
) To lock the folder again, repeat step 10 and step 11. Let me know if you get stuck somewhere.
