Used to query sector size information for a file system volume.

The FbwfFSInfo structure is identical to FILE_FS_SIZE_INFORMATION.

Syntax

typedef struct _FbwfFSInfo
{
      LARGE_INTEGER TotalAllocationUnits;
      LARGE_INTEGER AvailableAllocationUnits;
      ULONG SectorsPerAllocationUnit;
      ULONG BytesPerSector;
} FbwfFSInfo, *PFbwfFSInfo;

Members

  • TotalAllocationUnits
    Total number of allocation units on the volume that are available to the user associated with the calling thread.

    If per-user quotas are in use, this value may be less than the total number of allocation units on the disk.

  • AvailableAllocationUnits
    Total number of free allocation units on the volume that are available to the user associated with the calling thread.

    If per-user quotas are in use, this value may be less than the total number of free allocation units on the disk.

  • SectorsPerAllocationUnit
    Number of sectors in each allocation unit.
  • BytesPerSector
    Number of bytes in each sector.
