Copying attachments from one group library to another
I am trying to copy several hundred citations with pdf attachments from one Zotero group library to another. Each time I drag the citations with these attachments from the current location to the new library, only the citation information is copied to the new file, and the attachments (including pdfs) are all missing. How can I successfully transfer the citations while keeping all of the associated attachments together with the actual citation information.
If it is, delete the attachment-less items that are already in the group library, empty the trash, and drag again. Zotero won't currently add attachments to previously dragged items.
I have the "include child snapshots and imported files" box checked. I took your advice, deleted all the files in the new folder, emptied the trash and tried again to add the citations, but the same thing happens again.
Do you have any other suggestions how I might troubleshoot this?

Is the restriction on adding files to a public group still valid? Is it a copyright concern?
Is there any getting around this? I'd like to give my students access to a group library without compelling them to subscribe to any service. I certainly recommend Zotero to everyone, but I'd like to leave it to their choice to sign up.
