Re: Renaming / moving a folder with a lot of content : warning the user

Such operations are handled basically on the Zope level (CopyManager) and
there is no way to get hold of any kind of "progress" information without
extending the CopyManager API of Zope.
And for a move operation the complete old contents will be unindexed and the
new content will be indexed as well.  By default there is no way to
determine how expensive such an operation might be. From the Plone level you
might introspect the path index and get the number of objects in the related
subtree  - however not only the number objects matter but also there size
and type .
