What it does

Written by AI from the README

Scans your attachments from the Tools menu and tags items #duplicates or #broken as it finds duplicate or missing attachment files. It has no interface and works in the background.

Duplicate imports and PDFs deleted outside Zotero leave broken or repeated attachments. It has been superseded by Zotero Attachment Scanner.

How we pick these

By how closely what they do matches this plugin, using descriptions and the phrases people search with. Copies and forks of this plugin are listed under Forks and copies instead. No plugin pays to appear here.

Forks and copies

1 other plugin uses the same ID as this one. Every Zotero plugin carries an ID, a name tag Zotero uses to tell plugins apart. These 2 plugins carry the same one.Show what this means
  • You can only have one. Zotero sees them as the same plugin.
  • Installing another replaces it. If you install one of the others, it takes this one's place.
  • They do different things. The one you install may have nothing to do with the one it replaces.
