Convert converts the file allocation table (FAT) and FAT32 volumes into NTFS file systems, while the existing files and folders remain unchanged. Volumes converted to NTFS file systems cannot be converted back to FAT or FAT32.
grammar
convert[Volume]/fs:NTFS[/v][/CVT area:FileName][/no security][/x]
parameter
Volume specifies the drive letter to be converted to NTFS, followed by a colon, mount point, or volume name.
/fs: ntfs is required. Convert the volume to NTFS.
/v specifies verbose mode, that is, all messages will be displayed during conversion.
/cvtarea:FileName is only applicable to advanced users. Specifies that the master file table (MFT) and other NTFS metadata files are written to an adjacent existing placeholder file. The file must be in the root directory of the file system to be converted. If the /CVTAREA parameter is used, the converted file system will have less fragmentation. For best results, the file size is preferably 1 KB multiplied by the number of files and directories in the file system, but the conversion tool also accepts files of any size.
general idea
Before running convert, you must first create a placeholder file using the fsutil file createnew command. Convert will not create this file. Convert overwrites the file with NTFS raw data. After the conversion is completed, all unused space in the file will be released. For more information about the fsutil file command, see related topics.
/nosecurity specifies the security settings that everyone can access the converted files and directories.
/x If necessary, use this parameter to unmount the volume before conversion. Any open handles to this volume are no longer valid.
Example: Convert the system disk to NTFS format: (assuming that the C disk is a system partition)
Transform C: /fs:ntfs
