On my site I have quite a lot of Photo's meta_type=['Photo'] and they cause the zexp file to become very very very big (currently 86 Mb for 180 Photos). I would like to export my whole site but skip certain paths or meta types. The best way would be to write a little External Method or Python Script that calls manage_exportObjects() with a filtered object. I just need help to create the new copied object. I tried something like this: copy_of_self = self.copy.__deepcopy__() self.manage_exportObjects(filterbymetatypes(copy_of_self, ['Photo']) ) but copy woun't let me do that. if I had a copy of the object to be specially exported I could...: def fliterbymetatypes(object, metatypes=[]): objects = object.objectValues() for obj in objects: if obj is isPrincipiaFolderish(): # go further filterbymetatypes(obj, metatypes) elif obj.meta_type in meta_types: object.manage_delObjects([str(obj.id)]) ...or something like that (syntax might be bad, but you get the idea) Does anybody have a good solution? Or something to give me a better start. Peter
