Disclosed are systems, methods, and non-transitory computer-readable storage media for managing content item collections. For example, in embodiment, a client device may receive first user input selecting a content item collection. The client device may generate a graphical user interface for presenting the content item collection. The content item collection may include one or more tiles. Each tile may correspond to a content item embedded into the content item collection and stored by a content management system. The client device may present the content item collection including the one or more tiles. The client device may present, within each of the one or more tiles, an image representing the corresponding content item.

System and method of adding content items to a content management system

Disclosed are systems and methods of accessing content items stored at a content management system by a mobile device, when the mobile device is not communicatively coupled to the content management system. The content management system can receive an indication to mark a content item (e.g., folder and the content items associated with the folder) as available to a mobile device when the mobile device is offline. The content management system can mark the content item, and any content items associated with the content item, for offline access by the mobile device and determine a synchronization schedule for the content item(s). The content management system can then initially send to the mobile device, the marked content item(s) in accordance with the synchronization schedule. While offline, the mobile device can make changes to the marked content items. The changes can be synchronized between the mobile device and content management system when the mobile device is online.

Accessing network based content items by a mobile device while offline

The present disclosure generally relates to managing content item collections. A collection management system receives a request for collection item metadata associated with a collection item. Collection management system obtains a content item identifier corresponding to the collection item identifier. Collection management system requests content item metadata from a content management system. Collection management system receives from the content management system content item metadata corresponding to the content item identifier. Collection management system filters the content item metadata to remove a portion of the content item metadata comprising privileged information. Collection management system retrieves collection item metadata using the collection item identifier. Collection management system adds the filtered content item metadata to the collection item metadata. Collection management system sends to the client device the collection item metadata for the content item to be displayed, without sending the portion of the metadata comprising privileged information.

Managing content item collections

The present technology pertains to responding to a kernel level file event for a content item and presenting a file event window associated with the content item. A client device can detect the kernel level file event for the content item. This can be accomplished using a kernel extension on a client device that is networked with a content management system. The client device can then retrieve data associated with the content item, including an instruction for the content item. The client device can then perform the instruction. This instruction can be to retrieve collaboration data from the content management system and present the collaboration data in a file event window.

Kernel event triggers for content item security

The disclosed technology addresses the need in the art for providing workflow controls to shared content items stored on client devices, and enforcing content item check outs or content item locks for shared content items stored and accessed on client devices. The present technology further includes automatically locking a shared content item that is edited on a client device so that other team members cannot modify the content item. Accordingly, the present technology improves upon existing systems that provide workflow controls such as file check-in and checkout functionality by permitting users to access content items directly from the file system of their client device, and by providing automatic checkout and check-in functionality.

Workflow function of content management system enforced by client device

Disclosed are systems, methods, and non-transitory computer-readable storage media for copying content from a rendered document into another document. The disclosed technology addresses the need in the art to maintain a version of a collection of content items that includes changes and/or comments from a first group of users, and provide a second version of the collection of content items to an external user that does not include internal comments and/or visible changes. The solution may provide a work product that appears complete and/or professional to the second group of users, while the first group of users continue to update and/or collaborate on the first version of the collection of content items.
