Folder problem

[Shao Sean]

put the defaultFolder into the oldDefaultFolder -- if you require this (see
note 1 below)
answer folder "WhichOne"
if (it is not empty) then
  set the defaultFolder to it
  if (the number of lines in the files = 0) then
    #empty folder
  else
    #non-empty folder
  end if
end if


note 1:
storing the old defaultFolder at the beginning of your code allows you to
reset it at the end so the path that was there before is there again (other
code may be accessing it after your code and this allows you to be friendly
=)
