A. Windows 2000 and later support FAT, FAT32, and NTFS file systems. (The next version of Windows, code-named Longhorn, will support a new file system known as WinFS). The table below lists the maximum volume sizes and maximum file sizes for FAT, FAT32, and NTFS.
|Operating systems||All versions of Windows and DOS||Windows .NET Server 2003, Windows XP, Windows 2000, Windows 98, Windows 95 OEM Service Release (OSR) 2||Windows .NET Server 2003, Windows XP, and Windows 2000 support NTFS 4 and 5 (previous version of Windows NT support NTFS 4 only)|
|Maximum volume size||4GB||2TB (although Windows XP lets you format only up to 32GB but can read larger volumes)||You can use 64KB clusters to achieve a 256TB volume (any volumes larger than 2TB must be dynamic, not basic)|
|Minimum volume size||Floppy disk||512MB||10MB (although some tools let you format a floppy drive as NTFS, see Sysinternals.com)|
|Maximum file size||4GB||4GB||Size of volume|
|Maximum files per volume||512 files or folders per folder *||65,534 files or folders per folder *||4,294,967,295|
* If you use long filenames, you will reduce the number of files per folder.
