When the Zotero Connector saves a paper, looks in your Downloads or other folders for a PDF you already have and links it instead of keeping a second copy.

Downloads a .xpi file (0.02 MB). In Zotero, open Tools → Plugins and install it from the file.
In useAn estimate of how many copies of Zotero have it: Zotero downloads each new version once for every copy that has the plugin, so we count the downloads of its most-downloaded recent release. Rounded. Plugins that update from outside GitHub count low.
63
DownloadsAll-time downloads of its release files from GitHub, counting every update. Installs from elsewhere aren't counted.
63
ReleasesVersions published on GitHub. Everyone who has the plugin downloads each one again, which adds up in Downloads.

When the Zotero Connector saves a paper, looks in your Downloads or other folders for a PDF you already have and links it instead of keeping a second copy. Then checks for duplicate items and offers to merge. Also runs from the right-click menu.
Saving a paper through the Connector can leave two copies of the PDF and duplicate entries, with your annotations in the original. This links the file you have. Documented in Chinese.
