Although the end goal is laudable, I don''t like the corruption of FULLNAME -- especially the generalization of the RECOG argument, since it''s not at all clear that the other functions that take RECOG arugments could fit into the generalization.'
'
Peeking ahead in the mails, I see Kelly''s suggestion for GETDEVINFO and GETDIRINFO;  These would, I think, be preferable to overloading the functionality of FULLNAME and GETFILEINFO (the latter of which ought to return a stream/file-specic piece of information).'

I am inclined to agree that you are overloading GETFILEINFO, and you are certainly overloading FULLNAME, since DIRECTORY is in no way analogous to other values of RECOG.'
'
But in the case of FULLNAME, there already is a perfectly fine function DIRECTORYNAMEP.  We could simply tighten up its definition to require returning the full directory name, much as INFILEP returns a full file name.  At least the Leaf version of this already does coerce to canonical names': (DIRECTORYNAMEP ''{ROSE}<LISP>) => {ROSEBOWL}<LISP>.'
'
I like GETDIRINFO.  I could imagine combining GETDEVINFO and GETDIRINFO if we want to avoid proliferating names, but it would probably be cleaner to keep them separate.'
'
And what about a generic CREATEDIRECTORY?'
