FileSystemInfo.Refresh takes a snapshot of the file from the current file system. Refresh cannot correct the underlying file system even if the file system returns incorrect or outdated information. This can happen on platforms such as Windows 98.

Calls must be made to Refresh before attempting to get the attribute information, or the information will be outdated.
