(a) If the problem is answered on a server running LON-CAPA 2.10:


would give a comma separated list of paths of files submitted to the  
resource: upload in part: spdsht.

This list would include both files "submitted" to the essayresponse  
problem from the student's portfolio, and also files uploaded directly  
from the student's computer ("Browse" button), in this later case the  
path to the each file begins: /turned_in/  (and the files are stored  
internally within the student's portfolio in the /turned_in/ directory.

(b) If the problem is attempted on a server running LON-CAPA 2.9 or  
earlier, the presence of a directly uploaded file to a response item:  
upload in part: spdsht, will be indicated by:


This would give the url for the file (stored in a directory hierarchy  
in the course in this case).

The presence of files "submitted" from the portfolio will be indicated  
by the contents of  
&EXT('user.resource.resource.spdsht.upload.portfiles')  -- the same as  
for submission from a server running LON-CAPA 2.10.
