File Allocation Table, or FAT, is a filing system used in computer memory systems and cards, such as those manufactured by SanDisk. There are 12-, 16- and 32-bit versions of the FAT system. Because of the significant amount of memory capacity associated with the SanDisk card, it is a popular choice for portable data storage. While the FAT system is used less often than NTFS, it is still used by those who wish to use it on both PCs and Macs.
Step 1
Insert the SanDisk card into a multi-card reader. New computers usually come with a multi-card reader. If you don't have one, you can purchase internal and external readers. Make certain the SanDisk card is in the correct slot on the multi-card reader.
