[Zope] Folder upload ?

Hi, Could anyone tell me, if it is possible to upload a whole folder with all its including objekts like pictures and things into ZOPE? If yes, tell me how, please. And another question: a created my own zclass ( a newsitem). One instance of this newsitem has the same function like a folder. I can upload for example a file in it with the tag: <dtml-with News1> <dtml-call manage_addFile(... It works perfect :-) But I cannot insert something with the copy and paste functions in zope! If I try it, I get the message: The object 'file' does not support this operation. Perhaps someone is able to solve my probs ... Thanx, Marc
