    Abstract: The present technology pertains to synchronizing contents of a directory external to a synchronized directory by a content management system. The content management system is configured to synchronize only objects in the synchronized directory. Accordingly, the present technology creates an anchor object that represents the directory external to the synchronized directory within the synchronized directory. The anchor object includes special attributes that indicate to the synchronization client that the anchor object represents an external directory, and allows the contents of that directory to be synchronized directly to a server on the content management system without first storing the contents of the external directory on the hard drive of the client device.

    Abstract: The disclosed embodiments provide a system that facilitates searching an online content management system for content items associated with a user. During operation, the system receives a call from a client application at a search interface in the online content management system, wherein the client application is operating on behalf of the user. In response to the call, the system performs a lookup in a per-user index within the online content management system, wherein the per-user index facilitates looking up information about content items associated with the user in the online content management system. The system then returns the information obtained during the lookup to the client application. The client application can then use the retrieved information to facilitate an interaction between the client application and the user.

    Abstract: In some examples, a system for server-side rendering of password-protected files can receive, from a client device, a request to view a file on the system, determine that the file should be converted to a different format prior to presentation at the client device, and determine that the file is a password-protected file. The system can send a response to the client device indicating the file is a password-protected file. In response to receiving the password from the client device, the system can generate, based on the password, a preview of the password-protected file including at least a portion of the password-protected file rendered in the different format. After generating the preview, the system can store an encrypted copy of the preview in storage for future requests, and send the preview to the client device.

    Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that can leverage a natural language model to determine a most probable candidate sequence of tokens and thereby generate a predicted user activity. In particular, the disclosed systems can tokenize activity event vectors to generate a series of sequential tokens that correspond to recent user activity of one or more user accounts. In addition, the disclosed systems can, for each candidate (e.g., hypothetical) user activity, augment the series of sequential tokens to include a corresponding token. Based on respective probability scores for each of the augmented series of sequential tokens, the disclosed systems can identify as the predicted user activity, a candidate user activity corresponding to one of the augmented series of sequential tokens associated with a highest probability score. Based on the predicted user activity, the disclosed systems can surface one or more suggestions to a client device.

    Abstract: The present technology addresses a scenario when a user attempts to create a cloud content item using a file system interface on a client device. The present technology can immediately create a content item that is representative of a cloud content item once the user requests a cloud content item to be created. The content item that is representative of the cloud content item can be created even before the cloud content item itself is created. After the cloud content item is created, the present technology provides a mechanism to relate the content item that this representative of the cloud content item with the actual cloud content item.

    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for managing email attachments in an online content management system. In some implementations, a messaging client can receive input attaching a content item to an electronic message in a message thread. In response to the input, the messaging client can store the content item in a file system managed by an online content management system, generate a link to the content item, and insert the link in the electronic message. The content item can be shared with the recipients of the electronic message such that the content item can be synchronized across recipient devices by the online content management system. The messaging client on each recipient device and/or the sender's device can present representations of the attachments associated with the message thread in a centralized location on a GUI of the messaging client.

    Abstract: A content management system synchronizes content items across client computing systems connected by a network. Each client device has a storage allocation for synchronized shared content items. If the 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, or open a large content item remote to the client device, 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 for the initial request to be completed while maintaining user access to all synchronized shared content items.
