A hard drive file system means ‘how the operating system stores data on the drive’. There are different hard drives formatting used by Mac, Linux, Windows operating systems. In general, there are three common filesystems, which are used i.e: HFS+, NTFS, and FAT32. However, these file systems are not compatible with every operating system.

Answer is FAT32 has some limitations on file size however, it can work with 4GB larger file size but, this filesystem is outdated as compare to growth of computers technology. Since, it is cross operating system compatible so, still widly used by people. Users do format their disk and assigned different filesystem as per work requirements.
