Files: Quip, Private Files on Records, and Improved Search

Create, share, and collaborate on documents with Quip without an external file provider. Attach a file to a record and keep it private, or share it with the people and groups you choose. Files search results are now sortable with more fields.
Files and Files Connect for cloud-based external data sources are available in: Professional, Enterprise, Performance, Unlimited, and Developer Editions

Files Connect for on-premises external data sources is available for an extra cost in the same editions.
