FILE_FULL_DIR_INFO structure

Contains directory information for a file. This structure is returned from the GetFileInformationByHandleEx function when FileFullDirectoryInfo or FileFullDirectoryRestartInfo is passed in the FileInformationClass parameter.

Syntax


typedef struct _FILE_FULL_DIR_INFO {
  ULONG         NextEntryOffset;
  ULONG         FileIndex;
  LARGE_INTEGER CreationTime;
  LARGE_INTEGER LastAccessTime;
  LARGE_INTEGER LastWriteTime;
  LARGE_INTEGER ChangeTime;
  LARGE_INTEGER EndOfFile;
  LARGE_INTEGER AllocationSize;
  ULONG         FileAttributes;
  ULONG         FileNameLength;
  ULONG         EaSize;
  WCHAR         FileName[1];
} FILE_FULL_DIR_INFO, *PFILE_FULL_DIR_INFO;

Members

NextEntryOffset

The offset for the next FILE_FULL_DIR_INFO structure that is returned. Contains zero (0) if no other entries follow this one.

FileIndex

The byte offset of the file within the parent directory. This member is undefined for file systems, such as NTFS, in which the position of a file within the parent directory is not fixed and can be changed at any time to maintain sort order.

CreationTime

The time that the file was created.

LastAccessTime

The time that the file was last accessed.

LastWriteTime

The time that the file was last written to.

ChangeTime

The time that the file was last changed.

EndOfFile

The absolute new end-of-file position as a byte offset from the start of the file to the end of the default data stream of the file. Because this value is zero-based, it actually refers to the first free byte in the file. In other words, EndOfFile is the offset to the byte that immediately follows the last valid byte in the file.

AllocationSize

The number of bytes that are allocated for the file. This value is usually a multiple of the sector or cluster size of the underlying physical device.

FileAttributes

The file attributes. This member can be any valid combination of the following attributes:

FILE_ATTRIBUTE_ARCHIVE (0x00000020)
FILE_ATTRIBUTE_COMPRESSED (0x00000800)
FILE_ATTRIBUTE_DIRECTORY (0x00000010)
FILE_ATTRIBUTE_HIDDEN (0x00000002)
FILE_ATTRIBUTE_NORMAL (0x00000080)
FILE_ATTRIBUTE_READONLY (0x00000001)
FILE_ATTRIBUTE_SYSTEM (0x00000004)
FILE_ATTRIBUTE_TEMPORARY (0x00000100)
FileNameLength

The length of the file name.

EaSize

The size of the extended attributes for the file.

FileName

The first character of the file name string. This is followed in memory by the remainder of the string.

Remarks

The FILE_FULL_DIR_INFO structure is a subset of the information in the FILE_ID_BOTH_DIR_INFO structure. If the additional information is not needed then the operation will be faster as it comes from the directory entry; FILE_ID_BOTH_DIR_INFO contains information from both the directory entry and the Master File Table (MFT).

No specific access rights are required to query this information.

All dates and times are in absolute system-time format. Absolute system time is the number of 100-nanosecond intervals since the start of the year 1601.

This FILE_FULL_DIR_INFO structure must be aligned on a LONGLONG (8-byte) boundary. If a buffer contains two or more of these structures, the NextEntryOffset value in each entry, except the last, falls on an 8-byte boundary.

To compile an application that uses this structure, define the _WIN32_WINNT macro as 0x0600 or later. For more information, see Using the Windows Headers.
