WIN32_FILE_ATTRIBUTE_DATA (Windows Embedded CE 6.0)

1/6/2010

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

Syntax

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
  Attribute information for the file or directory. The following table shows possible values.

  Value	Description
  FILE_ATTRIBUTE_ARCHIVE	Indicates that the file or directory is an archive file or directory. Applications use this attribute to mark files for backup or removal.
  FILE_ATTRIBUTE_COMPRESSED	Indicates that 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	Indicates that the handle identifies a directory.
  FILE_ATTRIBUTE_ENCRYPTED	Indicates that 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	Indicates that the file or directory is hidden. It is not included in an ordinary directory listing.
  FILE_ATTRIBUTE_INROM	Indicates that this file is an OS file stored in ROM. This type of file is read-only; It cannot be modified.
  FILE_ATTRIBUTE_NORMAL	Indicates that the file or directory has no other attributes set. This attribute is valid only if used alone.
  FILE_ATTRIBUTE_READONLY	Indicates that 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	Indicates that the file has an associated reparse point.
  FILE_ATTRIBUTE_ROMMODULE	Indicates that the file is an OS file stored in ROM and run directly from ROM, rather than being first copied to RAM. You cannot use the CreateFile function to access this file. Instead, you must use the LoadLibrary and the CreateProcess functions.
  FILE_ATTRIBUTE_ROMSTATICREF	The file is a DLL module that has a static reference from at least one other file that is in the modules section of the image. A file with this attribute cannot replace the functionality of the DLL with a RAM copy of the same DLL. A file with this attribute must also have the FILE_ATTRIBUTE_INROM and the FILE_ATTRIBUTE_ROMMODULE attributes.
  FILE_ATTRIBUTE_SPARSE_FILE	Indicates that the file is a sparse file.
  FILE_ATTRIBUTE_SYSTEM	Indicates that the file or directory is part of the OS or is used exclusively by the OS.
  FILE_ATTRIBUTE_TEMPORARY	Indicates that 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. The application should delete a temporary file as soon as it is no longer needed.

• ftCreationTime
  FILETIME structure containing the time at which the file was created. The GetFileAttributesEx function reports 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 member. 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
  FILETIME structure containing the time at which the file was last accessed. The time is in UTC format. The FILETIME members are set to zero if the file system does not support this member.

• ftLastWriteTime
  FILETIME structure containing the time at which the file was last written to. The time is in UTC format. The FILETIME members are set to zero if the file system does not support this member.

• nFileSizeHigh
  High-order DWORD of the file size. This member has no meaning for directories.

• nFileSizeLow
  Low-order DWORD of the file size. This member has no meaning for directories.

Remarks

Not all file systems can record creation and last access time, and not all file systems record them in the same manner. For example, the object store (RAM) file system maintains only the last modified time.

Requirements

Header	winbase.h
Windows Embedded CE	Windows CE 3.0 and later
