    Abstract: The disclosed technology relates to a system configured to compute a difference between a local tree data structure representing a file system state for content items associated with a user account on the computing system and a sync tree data structure representing a known synchronization state between a content management system and the computing system. The system is configured to generate, based on the difference, a set of operations that when performed update the content items stored on the content management system to converge a server state for content items associated the user account on the content management system and the file system state.

    Abstract: A content management system synchronizes content items across client computing systems connected by a network. If a storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space while maintaining user access to all synchronized shared content items. Entries in a file journal may be used to track and manage whether a stored item is a content item or a shadow item.

    Abstract: A content management system can maintain the entirety of a user account's content library. As a default behavior, updates made to the content library when accessed from any client device authorized by the user account, including adding, modifying, and/or deleting content items, can be synchronized across all other authorized client devices. A user can opt out of the default behavior and specify, for each authorized client device, certain portions of the content library that the content management system should or should not synchronize.
