Oh, that's OK, I appreciate the input. Besides I learned more by trying =
your exammples.
I did figure out my problem today, though. Under the LocalFS object's =
properties, I had to select 'Catalog' to make it work. Once I did that, =
the dtml-tree worked fine.
<dtml-tree zinesfolder branches=3D"objectValues" sort=3D"meta_type">
<img src=3D"<dtml-var icon>">=20
<a href=3D"/zinesfolder/<dtml-var tree-item-url>"><dtml-var id></a>
</dtml-tree>
If I used this: branches_expr=3D"objectIds()"
it didn't work. (as in nothing displayed, but I didn't get any errors.)
I noticed that the LocalFS objects don't have the same properties(like =
title) as they do in Zope. I should expect that since they aren't =
actually "Zope" objects, rather LocalFS objects.
Now I just need to figure out how to get better icons to display, but =
that's not urgent. Thanks for your help!

I am sorry, I probably didnt explain my setup properly. The functions=20
that I use are for my use only. You dont necessarily need to use them to =
do what you want.
The minimal thing yoou can do is the following:
<dtml-let root=3D"zinesfolder">
<dtml-tree name=3Droot branches_expr=3D"objectIds()" nowrap single>
<dtml-var id>
</dtml-tree>
</dtml-let>
This will display your tree (with all the members in there).
If you do the following:
<dtml-let root=3D"zinesfolder">
<dtml-tree name=3Droot nowrap single>
<dtml-var getId>
</dtml-tree>
</dtml-let>
This wil show all the folders int your LocalFS instance.
If you want more functionality please provide some more specs and mebb I =
can help
