The following review written by one of the Software Informer contributors applies to version 7.3
Folder Lock provides you with several strong methods to protect your files and folders. The program allows you to hide them, encrypt them, and to create online backups of them. Moreover, you can also protect your portable media (such as pen drives and CD/DVD discs) and create virtual wallets to keep your credit card, bank account, and personal information safe.
The program offers you a neat and intuitive user interface where all the elements are self-descriptive. The first time you run the program, it will ask you to define your master password, which is the only one that will grant you access to your protected data from now on. So, it’s very advisable that you keep it in a safe place. Folder Lock offers you a separate section for each one of the functions offered through a tabbed panel. The first one is "Lock Files", and its main function is to allow you to hide your files/folders. You can add new files/folders to the protection list either by using the program's "Add" function or by dragging your files from Windows Explorer.
The second section of the program is "Encrypt Files", and its function is to allow you to create "lockers", which are encrypted containers you can add files to or extract files from. These lockers are encrypted using 256-bit AES technology, so that your files and folders are strongly protected. You need to set up a password for each locker, and when you open one, the program will automatically assign a drive letter to it (e.g., "Z:"), so you can use it as if it were a virtual disc.
Next section is "Secure Backup". It allows you to create backups of your local files and folders on online lockers, though you need to sign up and create an account first to be able to use this service. The "Protect USB/CD" feature allows you to create executable lockers – or make your existing lockers executable – and save them on your portable media. This way, you can carry your sensitive information with you fully encrypted and password-protected.
Finally, the "Make Wallets" section allows you to create virtual wallets, which behave in a similar way than lockers. Wallets are also password-protected and you can open or close them. Once you open a wallet, you can add/remove the information of as many credit cards as you need. From now on, your credit card information will be secure and strongly protected.
Summing up, Folder Lock is a powerful app that provides you with several helpful methods to protect your private and sensitive information. This program uses a very innovative concept when it comes to folder protection – virtual lockers. The program allows you to carry your private information with you in a safe way, and to keep your credit card information secure. Besides all the mentioned above, Folder Lock offers you even more protective functions, such as "Shred Files" (secure file deletion) and "Clean History" (secure deletion of your system usage tracks).
