 ## File systems
 
 File systems are what the computer relies on to ascertain the location and positioning of files on the disk. In Linux it is customary to use FAT-32 for the boot partition and ext-4 for the extended partition. In other operating systems you would do the same but most likely use NFTS for the extended partition.
