Iso, the international standard format of optical disk file system. The format of CD-ROM image file conforming to iso 9660 standard, and the file extension is usually iso. This kind of file can be simply understood as a mirror file formed by copying all the information on the CD.

In Windows operating system, special tools and software are generally needed to operate ISO files. For example, virtual cd software such as UltraISO, WinISO, WinImage, daemon tools, Alcohol 120%, WinMount, etc.

In Windows 7 operating system, there is a burning program. Compared with professional software, its function is relatively simple. Just right-click the iso file and select "Burn CD Image".

Benefits of iso:

1, high-speed CD

ISO files run directly on the hard disk at a speed of 200 x；; The response speed of the virtual CD-ROM is very fast, and the image file can be played smoothly without stopping. Generally, the transmission speed of hard disk is around 100- 150MB/S, which is equivalent to 1000X when converted into the transmission speed of optical drive (150K/S). Nowadays, most motherboards are integrated with Ultra DMA hard disk controller, and its transmission speed can be as high as 33M/S(220X).

2, the best companion for notebooks

ISO file can solve the problems of notebook computer without optical drive, too slow, difficult to carry and power consumption of optical drive. CD images can be copied from other computers or networks.

3. The best choice for Mo

ISO files can be stored in a MO disk, and then the MO disk becomes a "CD MO" when you carry it with you. MO optical drive integration, kill two birds with one stone.

Step 4 copy the CD

ISO files are very easy to manage; Instead of copying hundreds of files from CD to hard disk, this method may not work properly, because many CD software will need to run on CD-ROM drives, and deletion management is also a problem. Virtual cd completely solved these problems.

5. run multiple CDs.

Virtual cd can run multiple different ISO files simultaneously. For example, we can watch Encyclopedia Britannica on one CD-ROM drive, install PowerWord 2000 on another CD-ROM drive, and listen to CD records on a real CD-ROM drive. This requirement is impossible on the CD-ROM drive under any circumstances.

Step 6 compress ISO

Files are generally compressed and decompressed by professional algorithms. For some uncompressed files, the compression rate can reach more than 50%. Automatically decompresses when running, and the image playback effect will not be distorted.
