Fsutil: fsinfo

Typically used by support professionals. Lists all drives, queries the drive type, queries volume information, queries NTFS-specific volume information, or queries file system statistics.


fsutil fsinfo [drives]

fsutil fsinfo [drivetype] VolumePathname

fsutil fsinfo [ntfsinfo] RootPathname:

fsutil fsinfo [statistics] VolumePathname

fsutil fsinfo [volumeinfo] RootPathname:

Lists all drives in the computer.

Queries a drive and lists its type, for example CD-ROM drive.

Lists NTFS specific volume information for the specified volume, such as the number of sectors, total clusters, free clusters, and the start and end of the MFT Zone.

Lists file system statistics for the specified volume, such as metadata, log file, and MFT reads and writes.

Lists information for the specified volume, such as the file system, and whether the volume supports case-sensitive file names, unicode in file names, or disk quotas.

Specifies the drive letter (followed by a colon).

RootPathname :
Specifies the drive letter (followed by a colon) of the root drive.


To list all of the drives in the computer, type:

fsutil fsinfo drives

Sample output:

Drives: A:\ C:\ D:\ E:\       

To query the drive type of drive C, type:

fsutil fsinfo drivetype C:

Possible results:

  • Unknown Drive

  • No such Root Directory

  • Removable Drive, for example floppy
