No description available.
The FS_INFORMATION_CLASS enumeration contains the information class constants that specify what type of information structure is present for a set or a query operation.
FileFsVolumeInformation
Return a FILE_FS_VOLUME_INFORMATION structure that contains information about the volume such as the volume label, serial number, and creation time.
FileFsLabelInformation
Use a FILE_FS_LABEL_INFORMATION structure to set information a volume label.
FileFsSizeInformation
Return a FILE_FS_SIZE_INFORMATION structure containing information about the amount of space on the volume that is available to the user that is associated with the calling thread.
FileFsDeviceInformation
Return a FILE_FS_DEVICE_INFORMATION structure that contains device information for the volume.
FileFsAttributeInformation
Return a FILE_FS_ATTRIBUTE_INFORMATION structure that contains attribute information about the file system responsible for the volume.
FileFsControlInformation
Return a FILE_FS_CONTROL_INFORMATION structure that contains file system control information about the volume.
FileFsFullSizeInformation
Return a FILE_FS_FULL_SIZE_INFORMATION structure that contains information about the total amount of space available on the volume.
FileFsObjectIdInformation
Return a FILE_FS_OBJECTID_INFORMATION structure that contains file-system-specific object ID information for the volume. Note that this is not the same as the (GUID-based) unique volume name that is assigned by the operating system.
FileFsDriverPathInformation
Return a FILE_FS_DRIVER_PATH_INFORMATION structure that contains information about whether a specified driver is in the I/O path for the volume. The originator of the IRP_MJ_QUERY_VOLUME_INFORMATION request must store the name of the driver into the FILE_FS_DRIVER_PATH_INFORMATION structure before sending the IRP to the file system volume device stack.
FileFsVolumeFlagsInformation
Use a FILE_FS_VOLUME_FLAGS_INFORMATION structure to set the flags for a volume.
FileFsSectorSizeInformation
Return a FILE_FS_SECTOR_SIZE_INFORMATION structure that contains information about the physical and logical sector sizes of a volume.
FileFsDataCopyInformation
Returns a FILE_FS_DATA_COPY_INFORMATION structure that contains the number of data copies.
FileFsMetadataSizeInformation
Returns a FILE_FS_METADATA_SIZE_INFORMATION structure that contains the metadata size information.
FileFsFullSizeInformationEx
Returns a FILE_FS_FULL_SIZE_INFORMATION_EX structure that contains information about the total amount of space available on the volume.
FileFsGuidInformation
Returns a FILE_FS_GUID_INFORMATION structure that contains the GUID information.
FileFsMaximumInformation
