FAT32 provides no security in the file system, and you cannot limit who has access to the data as you can with NTFS.[] NTFSCorrect. NTFS is the recommend file system for Windows 10. NTFS has security that allows you to limit access to data based on permissions. The maximum size of an NTFS hard drive is 16 TB.
