3/26/2014

The following table shows the file system driver (FSD) structures with a description of the purpose of each.

Structure	Description
FILE_ALLOCATED_RANGE_BUFFER	Used with the FSCTL_QUERY_ALLOCATED_RANGES control code to indicate a range of bytes in a file. On input, the structure indicates the range of the file to search. On output, the operation obtains an array of FILE_ALLOCATED_RANGE_BUFFER structures to indicate the allocated ranges within the search range.
FILE_ZERO_DATA_INFORMATION	Used by the FSCTL_SET_ZERO_DATA control code to indicate a range of a file to set to zero.
FILTERHOOK	Contains function pointers to file system filter functions.
FSD_BUFFER_INFO	Contains buffer information.
FSD_DISK_INFO	Contains disk information.
FSD_SCATTER_GATHER_INFO	Contains information on data to be read from or written to the mounted volume.
FSD_SCATTER_GATHER_RESULTS	Contains the number of sectors transferred when calling the FSDMGR_ReadDiskEx or the FSDMGR_WriteDiskEx function.
FSD_VOLUME_INFO	Used with the FSD implementation of the FSD_GetVolumeInfo function to report information to the OS.
FILELOCKSTATE	Used by FSDMGR helper functions to track the state of all file locks associated with an open file in the file system.
