Check Your Storage
Zotero is a "freemium" software, allowing 300 MB of free storage with upgrade purchase options.
More info on Zotero storage plans here.
Check how much storage you have used by logging in to your account at zotero.org.
The boxes below describe some changes you can apply to your Zotero settings to maximize your free storage.
Remove Duplicates and Empty Trash
One copy of an item can be saved into multiple collections or folders. Right click on Duplicate items and merge identical duplicates.
To empty trash, right-click on Trash.
Do Not Automatically Save PDF
The majority of Zotero storage space is used by PDF attachments, so one way to save space is to uncheck "automatically attach associated PDFs"
