 This seems just to be a border case to multisessions on CD's for me, I'm
not convinced that it is 'standards-legal' to have it this way. It will most
likeley work in most cases.
 Here it seems as find and/or cygwin has problems in some undefined way. I
suspect that Chris probably has a great deal more clues about it ;-)

 I already know that the problem is _this particular CD_, as I said before;
it is the first in a set of three, on the other two 'find' does what is
expected.

 Come to think of it; might be something to try - if the above is indeed
true.
 I also have an idea on how to check for files with same contents (find,
md5sum, uniq - in combination).

 I have recollections of someone here... ahh... It _might_ be ME ;-)

My opinion and experience is that even the clueless can *at times* come up
with things that brings the discussion forth.
