In a shell in the directory <tt>repository</tt> I did:
<pre>zip ZZ *
mv ZZ.zip ../reposIntro</pre>
http://cap-lore.com/code/Scheme/reposIntro/ZZ.zip

It is the __MACOSX file in the containing directory where the 2nd write conflicts occur.
<p>
in directory norm do:
<br>diff -r cap*/code/Scheme/repository Downloads/repository | more
