File Systems
Windows XP Professional supports the FAT16, FAT32, and NTFS file systems. Because NTFS has all the basic capabilities of FAT16 and FAT32, with the added advantage of advanced storage features such as compression, improved security, and larger partitions and file sizes, it is the recommended file system for Windows Vista.
Some features that are available when you choose NTFS:
•
File encryption allows you to protect files and folders from unauthorized access.
•
Permissions can be set on individual files, as well as on folders.
•
Disk quotas allow you to monitor and control the amount of disk space used by individual users.
•
Better scalability allows you to use large volumes. The maximum volume size for NTFS is much greater than it is for FAT. Additionally, NTFS performance does not degrade as volume size increases, as it does in FAT systems.
•
Recovery logging of disk activities helps restore information quickly in the event of power failure or other system problems.
When you perform a clean installation of Windows Vista, it is recommended that you use NTFS. If you upgrade computers that use NTFS as the only file system, continue to use NTFS with Windows Vista.
Converting vs. Reformatting Existing Disk Partitions
•
Important You cannot upgrade compressed Windows 98 volumes; you must uncompress them before you upgrade them to Windows Vista.
Before you run Setup, you must decide whether to keep, convert, or reformat an existing partition. The default option for an existing partition is to keep the existing file system intact, thus preserving all files on that partition.
Windows Vista provides support for Windows 95, Windows 98, or Windows Me file systems, including FAT16 and FAT32 file systems. If you upgrade computers that use FAT or FAT32 as their file system, consider converting the partitions to NTFS.
Use the conversion option if you want to take advantage of NTFS features, such as security or disk compression, and you are not dual-booting with another operating system that needs access to the existing partition. You cannot convert an NTFS volume to FAT or FAT32. You must reformat the NTFS volume as FAT. However, when you convert a volume from FAT to NTFS, you cannot use the uninstall feature to roll back to a previous operating system installation.
•
Important Once you convert to NTFS, you cannot revert to FAT or FAT32.
You can reformat a partition during a clean installation only. If you decide to convert or reformat, select an appropriate file system (NTFS, FAT16, or FAT32).
Caution:
You can reformat a partition as either FAT or NTFS; however, reformatting a partition erases all files on that partition. Make sure to back up all files on the partition before you reformat it.
Multiple-Booting and File System Compatibility
NTFS is the recommended file system for Windows Vista. However, you might need a different file system to multiple-boot Windows XP Professional with an operating system that cannot access NTFS volumes. If you use NTFS to format a partition, only Windows XP, Windows 2000, and Windows NT 4.0 (with Service Pack 4) can access the volume.
If you plan to install Windows Vista and another operating system on the same computer, you must use a file system that all operating systems installed on the computer can access. For example, if the computer has Windows 95 and Windows XP Professional, you must use FAT on any partition that Windows 95 must access. However, if the computer has Windows NT 4.0 or Windows XP Professional and Windows Vista, you can use FAT or NTFS because both operating systems can access all those file systems. However, certain features in the version of NTFS included with Windows Vista are not available when the computer runs Windows NT 4.0. For more information about file system compatibility and multiple booting, see “Determining How Many Operating Systems to Install” in this chapter.
Important
•
You can access NTFS volumes only when running Windows Vista, Windows NT, Windows 2000, Windows Server 2003, or Windows XP.
