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. I...
