No. Try IBM's CMS. There are no notions of subdirectories there.
CMS's filenames are   "8char 8char 2char?" the last being a
minidisk name (a virtual disk which is a fixed partition of a real disk).
Other OSs allow large filenames, but still no real subdirs.

Even if you could depend on a directory tree, there may
be limits to its size, and how you go between levels of
the tree is different. 
In unix, you use . .. and /

In messydos use  . .. and \

On vaxen it works something like [-] for parent,
              and then [subdir.subdir2]file.ext;revision
Vaxen have troubles with directories deeper than 8. 

On amigas use <null string> for current dir, / for parent, : for root


What about devices that are in the filespace?
What about wild cards? They work differently on all of the above
implementations.

These are problems that would be hard to deal with in a general
fashion.
