Keep your files safe

Best Disk Lock is a computer application that is developed by Luoyang Xiabing Software Technologies Ltd to help keep your files safe and protected. It will lock away folders to prevent them from being opened and accessed by other people.

The ultimate protection 

There is more to Best Disk Lock than simply locking and blocking access to your folders. It offers 3 types of protection: Elementary, Intermediate, and Advanced. All of them will lock and hide your files from sight but the difference between the protection types is the way to find and access the hidden folders, drive, and files again. Those that are locked under Elementary or Advanced protection levels can be recovered by running a command line while files under the Advanced protection requires a more complex way to be accessed again. Having 3 different protection types makes Best Disk Lock friendly to all kinds of users. It will also help you properly lock hard drives and other data depending on how important and confidential they are.

Best Disk Lock can also prevent USB and other storage devices from being used on your computer. This means that files in your computer cannot be copied to any USB device unless you enable it. On the other hand, you can still view the files and folders stored in the USB by setting it in a read-only mode. Preventing USB access will help you keep your files from being unknowingly stolen or your computer from being infected by a virus.

The application is actually user-friendly despite its seemingly complex ways of keeping your files safe. Upon launching Best Disk Lock, you will find all the application’s functions arranged neatly at the top of the window. It will then provide you a ready list of your files and all you have to do is select which one you would like to lock, choose a protection level, and confirm. When unlocking files, you will also just have to click on the “Unlock disk” option on the lower part of the window. The interface of the software is simple, which makes it really easy to understand.
