Moving large number of items to a collection
I have several hundred items in My Library, but as I begin work on another project I'd like to copy these to a collection. I find I can drag two or three at a time but when I try select all and then attempt to drag these over, Zotero seems to choke and nothing is accomplished. Any other way to do this (besides doing a few at a time)? Thanks.
Zotero 2.0 won't try to generate Quick Copy output if you drag more than 50 items (configurable in the Export pane of the Zotero prefs). Zotero 1.0 will.
Regardless of what you do, you should probably drag batches of not more than about 50 items at once to your new collection(s) that should work.
