I am also having a problem dragging multiple PDFs into Zotero. I do have the checkbox toggled to "Automatically retrieve metadata for PDFs." Could there be another setting that needs to be tweaked to enable multiple PDFs to be added to one of my collections?
Also, I will echo the many thanks to the Zotero developers - this is a great tool!
While dragging, an icon with the number of PDFs appears with the subtext that says "copy" when hovering over the collection area. After releasing the finger from the mouse button, nothing happens.
Does dragging individual files works, or does it not work regardless of the number of files? Where are you dragging the files from? A normal local folder on your hard drive, or somewhere else?
Dragging individual files works great, with the creation of a parent item and metadata loading correctly. I experimented with dragging two files at once versus a whole folder full and received the same results. I also experimented by repeating the action with the metadata checkbox unselected, but this revealed identical results with no change. The files being attempted to transfer to Zotero were drug from a normal local folder on my hard drive.
Aloha - I am having this same issue here. I can drag one pdf at a time but I cannot drag more than one at a time (which I was able to do just a few weeks back, I believe). Thanks for any help/insights!
