    Abstract: The disclosed technology addresses the need in the art for synchronizing a content library between a content management system and client devices. Each content item in a user's content library is stored on the content management system and a record of each change to the content library is recorded in a content journal. A client device transmits a synchronization request that a portion of the content journal representing unsynchronized changes be processed to update the content library on the client device. The synchronization request includes a content library identifier and a content journal number identifying the content entry in the content journal last processed by the client device. Synchronization commands are sent based on the content entries not processed by the client device. Updated synchronization data representing the processed content entries is sent to the client device after synchronization is completed.

    Abstract: In some examples, a system can identify a plurality of contacts associated with a user account on a collaborative content management system, the plurality of contacts being associated with user accounts on the collaborative content management system. The system can obtain activity data associated with the plurality of contacts, the activity data identifying content interaction events at the collaborative content management system. Based on the activity data, the system can identify a portion of the content interaction events associated with one or more content items accessible to the user account and provide, to a user interface on a client device associated with the user account, a contact activity feed identifying the portion of the content interaction events and respective contacts associated with the portion of the content interaction events.

    Abstract: The present technology provides an interface and system for generating a previous version of a directory structure that can be useful in the restoration of a directory or file. The system, methods and non-transitory computer-readable storage media include receiving a request for a previous version of a directory structure at an indicated date, querying a content management system for placeholder content items associated with the previous version of the directory structure at the indicated date, receiving the placeholder content items, and generating a read-only copy of at least a portion of the previous version of the directory structure at the indicated date based on the placeholder content items, wherein the read-only copy of the directory structure is separate from the directory structure at a current date.

    Abstract: Systems, methods, and non-transitory computer readable media for dynamically selecting and sending content items to a user device based on various network and device conditions are provided. In some embodiments, a listing of images stored within a user account on a content management system may be generated, and a selection probability value may be assigned to each image within the listing. An available capacity level on the user device may be determined, and images may be dynamically selected to be sent to the user device based on the determined available capacity level and each image's selection probability value. In some embodiments, each image's selection probability value may be based on one or more factors. For example, images that have been recently viewed, recently added to a collection of images, and/or shared within a shared virtual space created by the user, may receive higher selection probability values than other images. In some embodiments, the selected images may be ranked in order of priority for transmission to the user device and sent to the user device in order of rank.
