Secret Disk can create additional disk on your PC, which can be invisible and locked with a password within one second. You can make your private files and folders invisible and protected. You don't need to format your hard disk or make any changes to boot sector. Our program will create new disk automatically very quickly. You can make this disk invisible, including all contents, and protect it with a password. You can store any files and folders on the disk. Secret disk works as usual hard disk and compatible with any other programs which you have installed. You can have more than one secret disk and you can also choose disk letter. In case of power outage or fatal error of OS Windows your secret disk will be locked and become invisible automatically. It happens automatically because information are stored in the virtual memory. Secret Disk does not encrypt any files, it just limits access to your files (you can use password). Software ties virtual disk to your files. This will provide you enough security to hide your files from any person.
