WIN32_FILE_ATTRIBUTE_DATA

The WIN32_FILE_ATTRIBUTE_DATA structure contains attribute information for a file or directory. The GetFileAttributesEx function uses this structure.

typedef struct _WIN32_FILE_ATTRIBUTE_DATA{ 
    DWORD      dwFileAttributes; 
    FILETIME   ftCreationTime; 
    FILETIME   ftLastAccessTime; 
    FILETIME   ftLastWriteTime; 
    DWORD      nFileSizeHigh; 
    DWORD      nFileSizeLow; 
} WIN32_FILE_ATTRIBUTE_DATA, *LPWIN32_FILE_ATTRIBUTE_DATA;

dwFileAttributes

A set of bit flags that specifies FAT-style attribute information for the file or directory.

The following attribute flags are defined:

Attribute Meaning

FILE_ATTRIBUTE_ARCHIVE The file or directory is an archive file. 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 of the data in the file is 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 data of the file 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 the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed..

ftCreationTime

Attribute	Meaning
FILE_ATTRIBUTE_ARCHIVE	The file or directory is an archive file. 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 of the data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.

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 the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed..

A FILETIME structure that specifies when the file or directory was created.

ftLastAccessTime

A FILETIME structure. For a file, the structure specifies when the file was last read from or written to. For a directory, the structure specifies when the directory was created. For both files and directories, the specified date will be correct, but the time of day will always be set to midnight.

ftLastWriteTime

A FILETIME structure. For a file, the structure specifies when the file was last written to. For a directory, the structure specifies when the directory was created.

nFileSizeHigh

Specifies the high-order DWORD of the file size. This member has no meaning for directories.

nFileSizeLow

Specifies the low-order DWORD of the file size. This member has no meaning for directories.
