WIN32_FIND_DATA

The WIN32_FIND_DATA structure describes a file found by the FindFirstFile, FindFirstFileEx, or FindNextFile function.

typedef struct _WIN32_FIND_DATA { // wfd 
    DWORD dwFileAttributes; 
    FILETIME ftCreationTime; 
    FILETIME ftLastAccessTime; 
    FILETIME ftLastWriteTime; 
    DWORD    nFileSizeHigh; 
    DWORD    nFileSizeLow; 
    DWORD    dwReserved0; 
    DWORD    dwReserved1; 
    TCHAR    cFileName[ MAX_PATH ]; 
    TCHAR    cAlternateFileName[ 14 ]; 
} WIN32_FIND_DATA;

Members

dwFileAttributes

Specifies the file attributes of the file found. This member can be one or more of the following values:

Attribute	Meaning
FILE_ATTRIBUTE_ARCHIVE	The file or directory is an archive file or directory. Applications use this attribute to mark files for backup or removal.
FILE_ATTRIBUTE_COMPRESSED	The file or directory is compressed. For a file, this means that all of the data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_DIRECTORY	The handle identifies a directory.
FILE_ATTRIBUTE_ENCRYPTED	The file or directory is encrypted. For a file, this means that all data streams are encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_HIDDEN	The file or directory is hidden. It is not included in an ordinary directory listing.
FILE_ATTRIBUTE_NORMAL	The file or directory has no other attributes set. This attribute is valid only if used alone.
FILE_ATTRIBUTE_OFFLINE	The file data is not immediately available. Indicates that the file data has been physically moved to offline storage.
FILE_ATTRIBUTE_READONLY	The file or directory is read-only. Applications can read the file but cannot write to it or delete it. In the case of a directory, applications cannot delete it.
FILE_ATTRIBUTE_REPARSE_POINT	The file has an associated reparse point.
FILE_ATTRIBUTE_SPARSE_FILE	The file is a sparse file.
FILE_ATTRIBUTE_SYSTEM	The file or directory is part of the operating system or is used exclusively by the operating system.
FILE_ATTRIBUTE_TEMPORARY	The file is being used for temporary storage. File systems attempt to keep all of the data in memory for quicker access, rather than flushing it back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.

ftCreationTime

Specifies a FILETIME structure containing the time the file was created. FindFirstFile and FindNextFile report file times in Coordinated Universal Time (UTC) format. These functions set the FILETIME members to zero if the file system containing the file does not support this time member. You can use the FileTimeToLocalFileTime function to convert from UTC to local time, and then use the FileTimeToSystemTime function to convert the local time to a SYSTEMTIME structure containing individual members for the month, day, year, weekday, hour, minute, second, and millisecond.

ftLastAccessTime

Specifies a FILETIME structure containing the time that the file was last accessed. The time is in UTC format; the FILETIME members are zero if the file system does not support this time member.

ftLastWriteTime

Specifies a FILETIME structure containing the time that the file was last written to. The time is in UTC format; the FILETIME members are zero if the file system does not support this time member.

nFileSizeHigh

Specifies the high-order DWORD value of the file size, in bytes. This value is zero unless the file size is greater than MAXDWORD. The size of the file is equal to (nFileSizeHigh * MAXDWORD) + nFileSizeLow.

nFileSizeLow

Specifies the low-order DWORD value of the file size, in bytes.

dwReserved0

If the dwFileAttributes member includes the FILE_ATTRIBUTE_REPARSE_POINT attribute, this member specifies the reparse tag. Otherwise, this value is undefined and should not be used.

dwReserved1

Reserved for future use.

cFileName

A null-terminated string that is the name of the file.

cAlternateFileName

A null-terminated string that is an alternative name for the file. This name is in the classic 8.3 (filename.ext) filename format.

Remarks

If a file has a long filename, the complete name appears in the cFileName field, and the 8.3 format truncated version of the name appears in the cAlternateFileName field. Otherwise, cAlternateFileName is empty. As an alternative, you can use the GetShortPathName function to find the 8.3 format version of a filename.
