Convert Existing Disk Volumes to NTFS

Updated: August 22, 2005

Applies To: Windows Server 2003, Windows Server 2003 with SP1

The command-line tool Convert.exe converts FAT and FAT32 volumes to the NTFS file system, leaving existing files and folder intact. Volumes converted to the NTFS file system cannot be converted back to FAT or FAT32.
