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;
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.. |
Windows NT: Requires version 4.0 or later.
Windows: Requires Windows 98 or later.
Windows CE: Unsupported.
Header: Declared in winbase.h.
