Dabaicai Super U disk boot creation tool, what do these four modes mean?

zip-fat32 and zip-fat16 refer to partition formats, while FAT16 can only have a maximum single file size of 2G, and FAT32 can have a maximum single file size of 4G. ZIP-FAT32 mode is more compatible with older computers.

HDD-fat32 and HDD-fat16 are hard disk emulation modes. They are both a type of File Allocation Table file system. They can be simply understood as the difference between 32-bit and 16-bit.

Zip-fat32 and zip-fat16 are a way of writing image files in compressed form. After DOS starts, drive A is displayed. The USB-ZIP bootable USB flash drive produced by FlashBoot adopts this mode. This mode is the only optional mode on some older computers, but it has poor compatibility with most new computers, especially large-capacity U disks. ?

HDD-fat32 and HDD-fat16 are hard disk emulation modes. After DOS startup, the C: drive is displayed. The U disk created by the HPU disk formatting tool adopts this startup mode. This mode has high compatibility, but it cannot be started for some computers that only support USB-ZIP mode. HDD-FAT32 mode is suitable for new computers.

Extended information:

FAT (File Allocation Table) means "File Allocation Table". It is a table used to record the location of files. It is very important for the use of the hard disk. If the file allocation table is lost, the data on the hard disk will not be able to be used because it cannot be located.

FAT16 uses 16-bit space to represent the configuration file of each sector (Sector), so it is called FAT16. ?

Because FAT16 is subject to innate limitations, every time a partition exceeds a certain capacity, the size of the cluster it uses must be expanded to accommodate the larger disk space. The so-called cluster is the allocation unit of disk space, just like the shelves in a library. Each file to be saved to disk must be configured with a sufficient number of clusters before it can be stored on disk.

FAT32 file system?

In order to solve the problems of FAT16, the FAT32 system was developed. FAT32 uses 32 bits of space to represent each sector (Sector) configuration file. The maximum single partition that can be used with FAT32 can reach 2TB (2048GB), and the size of the clusters that can be used for partitions of various sizes is also just right. The above two advantages make the use of hard disks more efficient.
