# fileLibraryItemsOnContact

Put Library items on a contact's Files & Photos, as the contact's Attach › From Library does: a snapshot copy of each file (up to 20, 300 MB each), and a PAGE as its PDF printed now as you see it. Ids are Library item ids (searchSpaceItems, listSpaceFolder, a page's id), never a chat artifactId. Returns each copy (`uploadedFileId`, `fileName`); undo with removeContactFiles (the copy's `uploadedFileId`). Never put a Library item on a record as a link.
