File System O The partition size, cluster size, maximum drive size, and maximum file size that can be used with a hard drive are determined by the file system being used. O For instance, Windows users have three file system options to choose from: 1. FAT file system (not commonly used today, but used with some removable storage devices like USB flash drives), 2. The newer FAT32 file system, 3. And the newest NTFS file system. File System O The recommended file system for computers running current versions of Windows is NTFS. O It supports much larger hard drives and files than either FAT or FAT32. O It includes better security and error-recovery capabilities. O Computers with older versions of Windows have to use FAT32, which has a maximum partition size of 32 GB and a maximum file size of 4 GB.
