WIN32_FILE_ATTRIBUTE_DATA
[New
- Windows NT]
The WIN32_FILE_ATTRIBUTE_DATA
structure contains attribute information for a file or directory. The GetFileAttributesEx function uses this
structure.
The
information contained in the WIN32_FILE_ATTRIBUTE_DATA structure is a
superset of the information returned by the GetFileAttributes function.
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;
Members
dwFileAttributes
A set of bit
flags that specifies FAT-style attribute information for the file or directory.
This is the same information that the GetFileAttributes function returns.
The following
attribute flags are defined:
|
Value |
Description |
|
FILE_ATTRIBUTE_ARCHIVE |
The file or
directory is an archive file or directory. Applications use this flag to mark
files for backup or removal. |
|
FILE_ATTRIBUTE_COMPRESSED |
The file or
directory is compressed. For a file, this means that all 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 file or directory
is a directory. |
|
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 from the file but cannot write
to it or delete it. In the case of a directory, applications cannot delete
it. |
|
FILE_ATTRIBUTE_SYSTEM |
The file or
directory is part of, 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
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.
