  • Publication number: 20240111397
    Abstract: The disclosure is directed to a document management system having a label management user interface. The document management system may be configured to display document content in either a document view mode or a document edit mode in which document content is displayed in a content panel of the graphical user interface. When in the document view mode and an authenticated user has edit permissions with respect to a current document, the graphical user interface is configured to display a label management user interface including an array of user-selectable label graphical objects and a list of recommended labels selected in accordance with a label score that is based on a set of multiple heuristics. Using the label management user interface, the user may transition from recommended label operations to a dynamic search operation and to a custom label creation operation without leaving the context of the current interface.

  • Publication number: 20240111399
    Abstract: A computer-implemented method for creating a new document space for a content collaboration system is disclosed. The method includes displaying a space-generation graphical user interface on a client device. The space-generation graphical user interface is displayed in response to a request for a new document space creation, and includes a first user input region, a second user input region, and a space-creation control. The method includes, in response to a user selection of the space-creation control, generating the new document space having a set of predefined space settings determined in accordance with a user selection of a particular selectable tab associated with a particular new-space type, generating space content having a space title determined in accordance with a proposed space title in the second user input region; and generating a new space path using a unique space key. The unique space key is generated based on the proposed space title.

  • Publication number: 20230004529
    Abstract: The present disclosure is directed toward systems and methods that efficiently and effectively generate and utilize collections of content items. For example, systems and methods described herein generate a collection content item including one or more content item references. In one or more embodiments, the collection content item can include content item references for content items located internally or externally, with granular levels of permissions settings and version controls. Additionally, in response to a detected selection of a content item reference, systems and methods described herein generate a rendering of the associated content item that can be viewed regardless of any third party software installed on the viewing client computing device.

  • Patent number: 11086823
    Abstract: Aspects of the subject technology relate to ways to avoid file duplication in a cloud storage service. In some aspects, a method of the technology includes steps for retrieving, via a computer network, one or more files from a first memory location, identifying a first signature and a second signature for each of the files, and storing the first signature and the second signature into a duplication reference list. In some aspects, the method further includes steps for analyzing files in a second memory location to identify duplicate files using the duplication reference list. Systems and computer-readable media are also provided.
