Hiya,
I wrote the following code to do it in magnolia 4.4... still needs a bit of
optimization as it's a bit slow at the moment.
I put this code in a magnolia "page" and made it accessible from the backend.
The same code could go in a servlet, or a model class, depending on how you
need it.
Regards from Vienna,
Richard

Betreff: [magnolia-user] Download DMS Zipfile
Is there a function to download a document tree as ZIP file from DMS?
Or maybe a Groovy script?
Thanks
