Just to be clear, this is the sort of thing one *can* do:

Suppose you have a quiz in a subject called test. Then one can do:

  1. Let's say the subject is subj. Then in

     WEB-INF/root/subjects/subj/quizzes

    one can do a recursive copy of test/ to tes2/, say:

      cp -r test tes2

  2. Now one has a directory tes2/ with identical contects to test/
     There is a .m file in tes2/ now called test.m
     This needs to be tes2.m. So do:

      mv test.m tes2.m
 
  3. Now this will work already but address thinks in the test/ directory
     So you need to edit the (appropriate) occurrences of test in tes2.m  
     to be tes2

     The ones underlined need to be changed to tes2.

Observe that each of these lines has 79 characters exactly. I guess the 
80th is an invisible newline character.

You will find that doing this at least on Linux all you have to do is
unhide the quiz and it works.

However if you try the same procedure but with a new directory name that
is of a different length to test then AIM says it can't load the quiz, and
that's even if you adjust each line to have exactly 79 characters in it.
It seems that the length of the file is recorded somewhere or something.

Manolis's message referred to copying a whole subject, but I'm sure the
same mechanism applies at the subject level as it does at the quiz level.
