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.
Each Zotero user is given 300 MB of free Zotero File Storage, with larger storage plans available for purchase. To sign up for additional storage, visit the storage settings of your Zotero account profile and select a storage plan. You can then configure your storage settings through your Zotero Sync preferences. You can view your current Zotero File Storage usage and quota in your Storage Settings.
Zotero File Storage services are provided by the Corporation for Digital Scholarship.

Closed public and private groups can use Zotero File Storage for file syncing as long as the group owner has storage space available and has opted to use Zotero File Storage for group files. Group file storage draws from the storage account of the group owner, not from the group's members. Group owners can freely allocate their storage usage between personal and group libraries. There are no restrictions on the number of group libraries that users can create and no limits on the number of users who may access these libraries.
