All of us have some files and folders that we consider private. They can be anything from our business documents to pictures of friends and family. These are files that we don’t want other people using our computer to know about. As Windows offers no way to protect our private information, most of us get in awkward situations when these files are discovered by unwanted people.
Surely, you can store this information in a hidden folder. The only problem is that anyone can easily search the contents of a hidden folder using Windows Search itself.
The only viable solution is storing this content in a password protected folder so that only those people knowing the password of the folder can access it. There are many folder locking programs available online but the problem is that most of the good ones are paid. Even if you do manage to get a good free one, you will be looked at suspiciously when people see a folder locker in the list of your installed programs.
If you too find yourself in a similar situation, you can try Folder Protector, a password protector for Windows folders that is not only free but is also portable meaning that it does not need to be installed. Just click on the exe file and the program will start running. I have created this program based on suggestions and feature requests that I have received by email over the last two years.
Folder Protector offers each user a protected folder that can only be opened by entering the password in FolderProtector. Unlike most security programs, Folder Protector is small in size (nearly 58KB) and does not show the folder that it is protecting. This gives an additional advantage that people who don’t know the password do not have a target to try and hack their way into. As the software is portable, you can hide it or even delete it after protecting your folder and no one will have a clue that it was used. Then whenever you need to access protected files, you can re-download the program from this page, enter the password and access your protected files.

How to use Folder Protector?
When you run Folder Protector for the first time, the program will ask you for a password that you want to use. Enter a password that you can remember as this will be the password to your protected folder.
After entering the password, the program will open a folder named SecuredFILES. This is your protected folder. You can add all your private files in this folder. This folder is located at the Desktop. After adding all your files, you may close this folder.
Then, you can use the menu in the program to lock your folder. To lock the folder, type lock as your action. After successfully locking the folder, FolderProtector will display that the folder is locked.
Unlocking the protected folder is easy. Just type unlock as your action. Then the program will ask you to enter your password. Upon successfully entering the password, the program will display the contents of your protected folder.
Changing the Password: Just type change as your action. The program will ask you for your current password. Upon successful entry of the current password, the program will ask for your new password and change it instantly.
Acknowledgment: This software has been made possible only through the suggestions of readers of this blog, especially Ernell Albert Galido for his idea of using a menu based interface.
Windows Compatibility: This program has been successfully tested on Windows 8, Windows 7, Windows Vista and Windows XP.
