here is no need to format your hard drive, our program creates virtual (not real) disk space instantly. The disk space will be taken from the existing disks, limited only by the physical size of your storage. This disk supports optional password protection to block unwanted access to it. It can store any file or folder and is compatible with all programs running on the Windows OS disk. When the disk is hidden it won’t appear in Explorer, as it doesn’t exist on the normal disk. The data stored on the disk is not deleted when the disk is in this hidden state.
