If there is some reason to dual boot the system, FAT16 allows you the greatest number of options. MS-DOS, Windows 95, Windows 98, Windows NT, Windows 2000, and some UNIX operating systems can use FAT16. In summary, there are "advantages" for using the FAT file system on a Windows XP Professional installation: You can obviously see that this is a serious problem when there are thousands of small *.DLLs and other types of small files.Īlso, with the advent of super-inexpensive hard drives that are 80GB in size, you can see where using FAT would be an issue as well. The larger the cluster size, the more space is "required" when using it to store data.Īs you can see, with a 2GB partition size, (the maximum allowed under FAT16 in most cases) if you were to save 50 different files, all 1024 bytes (1KB) in actual size (or to have 50 fractions of larger files "fall over" to the next cluster by that same amount), the amount of hard drive space used up would be 1,638,400 bytes (a little over 1 MB), for 51,200 bytes of actual data. The larger the partition, the larger the cluster size. Windows XP Professional supports the three major computer files systems of File Allocation Table (commonly known as FAT or FAT16), FAT32 and NTFS.įile Allocation Table (commonly known as FAT or FAT16) is supported by Windows XP Professional, all Windows operating systems, DOS, as well as a host of other non-Microsoft OSes.įAT is allocated in clusters, the size of which are determined by the size of the partition. One place to start would be the file system the operating system is utilizing. To have a good understanding of how and why you can set up or deny access to data on a Windows XP Professional system, you need to have an underlying understanding of any native file security that may or may not be in place. With this article I will begin focusing on the next section of material which centers on Implementing and Conducting Administration of Resources on Windows XP Professional, this one covering Windows XP Professional file systems.
