May I ask all computer professionals, what is the function of virtual discs?

In order to prevent piracy, some genuine software has come out with some CD-ROM software, that is, the use of the software must have a CD-ROM, and it cannot run without a CD-ROM. Most of them are used in games, many stand-alone games do not have a hard disk version, only a disc version, those who don't want to buy a disc can make a disc mirror with a virtual optical area simulation can be used as a disc.

A virtual disc is a virtual disc that you can load by installing a virtual drive on your computer, which looks like the contents of the disc.

You go to the next Deamon Tools on the Internet and load the img file on your computer to see what's going on.

That kind of file is like a disc stored in a computer, which can be opened with some virtual optical drive software.

Virtual Disc: A disc that you can't touch.

It needs to be opened with a virtual optical drive. Deamon Tools is a good example. After installing the virtual drive, it is inside my computer. You will find that there are 2 optical drives, 1 is real and 1 is virtual.

Insert the virtual disc into the virtual drive. It's just like a normal optical drive.

Turn this file into a virtual drive. This allows it to be used as an optical drive.

It is to install a software on the computer, and you can directly load the disc image, just like reading the disc with a CD-ROM drive!

Virtual discs and virtual discs are the same thing, and virtual optical drives are programs specially designed to read virtual discs and virtual discs.

1。What is a virtual optical drive?

Virtual optical drives are a general term for a class of software, and their use is to simulate 1 under the system

A disc drive! This optical drive does not exist in real life, but it can work like a real optical drive, so it is called a virtual optical drive.

2。What is the use of a virtual optical drive?

Because the real physical optical drive has a limited lifespan, in order to save the use of the optical drive, we use a virtual optical drive instead to prolong the use time of the physical optical drive.

3。Why Create an Image File?

The virtual optical drive does not exist realistically and cannot read real discs. Therefore, the virtual optical drive should establish its own optical disc that can be read, that is, the virtual optical disc, which is the image file we usually call the image file, its format.

Virtual optical drive is a kind of simulation (CD-ROM) working tool software, can generate and your computer installed optical driver can be exactly the same virtual optical allow, the general optical drive can do the same virtual optical drive can do, the working principle of this is to first virtualize one or more virtual optical drives, the application software on the disc, the image is stored on the hard disk, and generate a virtual optical drive image file, and then you can windows95 98 nt in the virtual optical drive to use, So when you want to start this application in the future, you don't need to put the disc in the optical drive, and you don't need to wait for the optical to start slowly, you just need to tap on the insert icon, and the virtual disc will be loaded into the virtual optical drive immediately, which is fast and convenient.

Common image file formats include ISO, BIN, IMG, TAO, DAO, CIF, and FCD

It is to use software to virtualize an optical drive, which is specially used to use the optical disc image (just like a virtual optical disc). Neither of these is the real thing. It's all the stuff of the computer's hard drive.

Some games can only be played by putting the disc in the CD-ROM drive. With a virtual CD-ROM drive, you can play by putting the ISO image file into the virtual CD-ROM drive. No more optical drives and discs.
