[Zope] Finding the right import folder

[Ron]

I have a Zope instance running on a FreeBSD (8) server.  Zope is running fine
(by all measures).  Here is the particulars of the system:

Zope Version
   (Zope 2.7.9-final, python 2.4.5, freebsd8)

Python Version
   2.4.5 (#2, Nov 10 2011, 00:37:52) [GCC 4.2.1 20070719 [FreeBSD]]

System Platform	
   freebsd8

SOFTWARE_HOME
	/usr/local/www/Zope/lib/python

ZOPE_HOME
	/usr/local/www/Zope

INSTANCE_HOME
	/usr/local/setp

CLIENT_HOME
	/usr/local/setp/var


Network Services
	
ZServer.HTTPServer.zhttp_server (Port: 8080)
ZServer.FTPServer.FTPServer (Port: 8021)

-------------------------------

The problem is that I need to import some .zexp files.  I would have thought
that I should put them in the (already existing) import folder at the
INSTANCE_HOME (i.e., /usr/local/setp/import) but when I restart Zope, none of
the .zexp files (including the standard Zope tutorial) show up in a pull-down
menu in the import page.  Based on the above, where should I put the .zexp files
so that the Zope instance finds them.
