LocK-A-FoLdeR Is The Simplest Way To Password Protect Your Folders

Want to protect confidential data on your PC without much hassle? You can use encryption software to encrypt data, hide it from frequently visited locations, or protect it with a staunch password. Generally, there are only few folders which we want to protect from unauthorized external sources, therefore, using an advanced encryption software makes sense only if you don’t have a reliable password protection tool which ensures data protection. LocK-A-FoLder is a small open source security tool for highly confidential data folders. It applies password protection to prevent your data from being easily accesable. Moreover, locking and unlocking folders hardly take a few seconds. Once locked, it will automatically hide the folder and keep it concealed even when users enable Show all files and folders option in Windows Explorer.

As of now, LocK-A-FoLder can lock only 3 folders. You just have to specify the folders which are to be password protected and it will hide and lock them instantly. The application protects itself with master password, which is also used for unlocking folders. Usage is simple. Just launch the application and it will prompt you to enter master password. Once entered, the main interface will show up.

lock folder

Click Lock a Folder, enter master password and choose the folders over which password protection is to be applied. Once paths are specified, click Lock it! to protect them from any unauthorized usage.

lock folders

Likewise, from the main interface, you can unlock password protected folders after entering the master password. You can even select all the locked folders and unlock them in one go.

LocK-A-FoLfeR works on Windows XP, Windows Vista, and Windows 7.

    It doesn’t work!

  • Jeff Huntington

    Worked for me, hid the folder. Now my question is: How do you find the file and how does this work with a backup service that scans and backs up your computer files? Seems like this would not be beneficial to encrypt your files if you can’t back them up.

      Hey Gurjit.
      Assuming you are the developer of this software,you have done a great job but i am in a kind of deadlock situation regarding this software.I have locked a folder which i am unable to unlock.It says “** cant be unlocked”.
      Also I cant uninstall it unless all folders are unlocked.
      Can you please help me out?



  • mak

    nice one ..its work

  • Connordupont

    Great Idea… Poorly made. You didn’t realize that if the person knows the name of the file they can just search for it in the start menu? (And this works I just tried it) Worst of all they don’t have to know the whole name of the file even if they know or guess the first two or three letters it will show up.

  • You suck

    I Thought this software was ok until i tried to unlock it.

  • Edwin

    This software does a half-ass job in hiding the folders you pick. Yes, visually it hides the folder so you can’t access it by clicking via Windows Explorer but all files contained in a locked folder still appear in a simple search via Start menu. Even worse, if you search for a file, then right click the filename in the results and select “Open file location”, it will open your “locked” folder. No password asked.

    • Edwin

      What good is “locking” a folder if you can jump right into it with a simple search?

    Bitdefender is blocking the download page due to malware detection.

  • Brown Jason

    Compression programs such as 7 zip, Winrar are good at file protection.
    Besides, Kakasoft Folder Protector is a good file encryption program, it’s able to protect folders on local computer and flash drives.
