DOS is still very useful in many situations. In addition to its many functions, DOS can also solve many problems that cannot be solved by other systems such as WIN. In these cases, it can show its talents. MS-DOS 7.10 is currently a practical pure DOS system with very good compatibility. It fully supports long file names, FAT12/16/32 partitions, oversized hard disks, etc., and can start DOS graphical operating platforms such as Win3.x/9x.
This is a complete installation version of MS-DOS 7.10, including its installation disk, which can automatically install the complete DOS system to the hard disk (including large hard disks). The installation program has a friendly and easy-to-use interface, and can automatically create MS-DOS 7.10 and their dual-boot when Win9x/NT/2K/XP+ and other systems have been installed in the system without affecting each other. It is very safe and practical.
If the system has an old version of DOS such as MS-DOS 6.22, it can also be directly upgraded to MS-DOS 7.10 to fully utilize and reflect the new functions and uses of DOS. For more details, please see the documentation inside.

Editor's comments
DOS is a glorious operating system for a long time. Although Windows is now shining brightly, DOS is still developing; and DOS also has its powerful functions and special functions that cannot be replaced by other operating systems, especially Windows.
DOS (Disk Operation System) was once a popular PC operating system around the world. However, due to Microsoft's "Windows Strategy", it has now almost become a "forgotten generation" in my country. The era of DOS as the mainstream operating system has passed. This is an indisputable fact. However, DOS has not disappeared because of Microsoft's abandonment. Instead, it still has many followers at home and abroad. Compared with Windows, DOS is more convenient and convenient to operate. It is faster, more stable, and more efficient, and it also has the underlying freedom and openness that Windows systems do not have. Therefore, treating DOS correctly is the source of new development of DOS!
