Note: File access security checking is performed at the directory level, rather than the file level.
If a specified file ID is not a fully qualified ID, the current directory or PATH directories are
used in an attempt to resolve the partial name into a fully qualified name; in this case no further
checking is necessary. If a fully qualified file ID is used, the directory it resides in is checked
for proper access authorization, at file open time.
