What is mirroring?

Mirroring is a form of file storage. The data on one disk is mirrored by the existence of an identical copy on another disk. Common mirror file formats include ISO, BIN, IMG, TAO, DAO, CIF, FCD, etc. The so-called mirroring file is actually similar to a ZIP archive, which is a series of files made into a single file according to a certain format to make it easier for users to download and use, for example, a beta version of an operating system, a game, etc. Not only does it have the “ZIP” function, but it also has the “ZIP” function, which makes it easier for users to download and use. Mirror files not only have the “synthesis” function of ZIP archives, but their most important feature is that they can be recognized by specific software and burned directly to CD-ROM. In fact, the usual sense of the image file can be expanded, in the image file can contain more information. For example, system files, boot files, partition table) information and so on, so that the image file can contain all the information of a partition or even a hard disk. The classic software for using this type of image file is Ghost, which also has a burning function, but its burning only saves the image file itself on the CD-ROM, whereas burning software in the usual sense can burn the contents contained in a supported image file directly onto the CD-ROM.
