Zotero File Storage is a cloud-based syncing and storage solution for PDFs, images, web snapshots, and any other files attached to your Zotero libraries. Zotero File Storage synchronizes the files in your personal Zotero library to all your computers, allows you to share the files in your group libraries, and makes files available through the zotero.org website.
Zotero offers a limited amount of free storage to everyone, and users can increase their storage limits by subscribing to one of our storage plans:
Individual subscriptions are aimed at individual researchers who aren't members of a lab or institution with an existing subscription.
Zotero Lab and Zotero Institution provide unlimited Zotero storage for an entire lab or institutional community.
