FAT 12 16 are two of the oldest file system here. Next, FAT32It was introduced all the way back in Windows 95 & 98 and DOS v7 and higher was around, and FAT32 increases the number of bits used to address clusters and also reduces the size of each cluster. The result is that it can support larger disks (up to 2 terabytes) and better storage efficiency (less slack space). FAT32 or (File Allocation Table) One of the prons of FAT32 is it is cross-platform compatibility, lightweight, but one of the cons it tops out at 4GB's. It also means that you are limited to 4GB files witch sucks. NTFS or (New Technology File System) witch Microsoft introduced on July 27, 1993, and was first used on Windows NT. And there are NO Limits. NTFScan support volumes as large as 256 terabytes. One of the pros is Inexhaustible limits for file and partition size, but one of the cons is Limited cross-platform compatibility. Good usage is Best for internal hard drives. Use it for Windows system drive and any other system partition which may be used to install software. exFAT (Extended File Allocation Table) is a Microsoft file system optimized for flash memory such as USB flash drives exFAT can be used where the NTFS file system is not a feasible solution. One of the pros is Behaves as a fusion between FAT32 and NTFS by providing practically unlimited file size and partition size, but one of the cons is Microsoft restricts its usage by license obligations. exFAT is mainly used on MAC computers like if u have big video files. Use with external hard drives or flash drives if you want to transfer files larger than 4 GB. Always prefer exFAT over FAT32, if the operating system supports it.
