Virtualize your CDs, DVD, HD DVDs and Blu-ray Discs and get the fastest possible access to your data, both locally and over the network. Virtual CD creates images of your optical media, so you can use them at any time without having the physical medium on hand. Your data is available exactly as if the medium was in the drive, without the disadvantages attendant, for example, on network shares. The images created can be stored on a server to enable simultaneous access by multiple users. When creating an image, you have the option of selecting the level of compression and, if desired, even encryption. You get maximum availability of your data, while lost, damaged and stolen media become a thing of the past. With a simple left click on the Virtual CD symbol you arrive at the program menu where you can utilize all important Virtual CD functions. If you click on the symbol with the right mouse key, the drive menu opens. Here you can e.g. insert and eject images or insert blank CDs in the virtual burner.

Shadow Defender is an easy-to-use desktop security and privacy protection tool for Windows operating systems. It provides an excellent way to prevent unwanted or malicious changes from being made to a PC. With Shadow Defender you can run system in a virtual environment, called Shadow Mode and all the attacks will happed in the virtual environment, not the real environment. If attacks happened, all you need to do is to reboot your system. After reboot, the system will be restored to the original state, as if nothing happened. And meanwhile you can save the selected files and folders to the real environment.
Shadow Defender's protection concept is very easy to grasp. For the software to do its job properly you have to place the disks installed on your computer into Shadow Mode. By doing this, the application will take a snapshot of the disk and run every file in virtual mode. You will have the same access to the files on the disk but any write action will be virtual.
