#What I'm trying to figure out is how to prevent someone from getting to
#all the files on the system by adding /.. to the path or something else
#more devious.  Now I could crack the path and look for a .. element or I
#could store all the possible paths in a database an use a key to access
#them.  I'm not sure there might not still be a security problem with the
#first option and the second option seems to be overkill, besides,
#displaying the path will be beneficial to the user.
