Property Value

The value of the LastWriteTime property is pre-cached. To get the latest value, call the Refresh method.

This method may return an inaccurate value, because it uses native functions whose values may not be continuously updated by the operating system.

If the file described in the FileSystemInfo object does not exist, this property will return 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC), adjusted to local time.
