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.

Abstract: A collaborative content management system allows multiple users to access and modify collaborative documents. When audio data is recorded by or uploaded to the system, the audio data may be transcribed or summarized to improve accessibility and user efficiency. Text transcriptions are associated with portions of the audio data representative of the text, and users can search the text transcription and access the portions of the audio data corresponding to search queries for playback. An outline can be automatically generated based on a text transcription of audio data and embedded as a modifiable object within a collaborative document. The system associates hot words with actions to modify the collaborative document upon identifying the hot words in the audio data. Collaborative content management systems can also generate custom lexicons for users based on documents associated with the user for use in transcribing audio data, ensuring that text transcription is more accurate.

Abstract: In some embodiments, upon detecting malicious activity associated with a user account, a content management system can identify other user accounts related to the malicious user account. The content management system can identify related user accounts by comparing authentication information collected for the malicious user account with authentication information collected for other user accounts. Authentication information can include IP address information, geographic information, device type, browser type, email addresses, and/or referral information, for example. The content management system can compare the content items associated with the malicious user account to content items associated with other user accounts to determine relatedness or maliciousness. After identifying related malicious user accounts, the content management system can block all related malicious user accounts.

Abstract: A document management system that is adapted to allow users to share files or folders by: (1) creating a link to the files or folders; and (2) sharing the link with other users. In particular embodiments, the system is adapted to keep track of any links generated by, sent by, and/or received by a particular user. The system may display a listing of the links upon request by a user, so that the user may re-use or deactivate the links, or modify attributes of the links. Having a centralized listing of the links may be particularly advantageous in helping a user keep track of the files and folders that they have shared and received.

Abstract: A computer-implemented method is provided for managing and sharing picture files. In one embodiment of the present invention, the method comprises providing a server platform and providing a datastore on the server platform for maintaining full resolution copies of the files shared between a plurality of sharing clients. A synchronization engine is provided on the server platform and is configured to send real-time updates to a plurality of sharing clients when at least one of the sharing clients updates or changes one of said files. A web interface may also be provided that allows a user to access files in the datastore through the use of a web browser.

Abstract: Described embodiments enable device users to share content items directly from the context of a desktop file system user interface. A share bar is displayed in the file system user interface, where the share bar includes one or more graphical control elements that provide additional functionality with respect to one or more selected content items in the user interface. The additional functionality can include sharing the selected item, moving the item, downloading the item, and viewing sharing status, version history, completion status, comments, or other information about the item.

Abstract: A content management system for collecting files from one or more submitters in a collection folder. A collector, who generates the collection folder, can invite one or more submitters to submit one or more files to the collection folder. Facial recognition is applied to the submitted files. The one or more submitters have limited rights to the collection folder. The limited rights can include uploading rights and prohibiting a submitter from viewing files that other submitters associated with the collection folder submitted. Thus, the collection folder is able to store files from the one or more submitters, but prevent them from viewing other's submissions.

Abstract: The present technology displays an access list, seen state information, and presence information for content items stored and managed by a content management system. Advantageously, the present technology does not require users to view or work on content items within the content management system—they can work on content items natively on their own computing device.

Abstract: The present technology pertains to a details pane that is displayed in coordination with a file explorer interface. The details pane can display details including activities, comments, and previews for content items displayed in the details pane. In some embodiments, the content items displayed in the file explorer interface can be stored in and accessed from different services, and the details in the details pane can also be populated from diverse sources. In some embodiments, edits or navigations can be performed within a preview of the content item. In some embodiments, comments can be shown along with previews that show the comment located within the content item.

Abstract: A content management system for collecting files from one or more authenticated submitters in a collection folder. A collector, who generates the collection folder, can invite one or more submitters to submit one or more files to the collection folder. The one or more submitters have limited rights to the collection folder. The limited rights can include uploading rights and prohibiting a submitter from viewing files that other submitters associated with the collection folder submitted. Thus, the collection folder is able to store files from the one or more submitters, but prevent them from viewing other's submissions.

Abstract: The present disclosure relates to generating and utilizing digital associations between digital documents and digital calendar events based on determined content connections. For example, one or more embodiments suggest a digital document to a user for association with a digital calendar event based on content connections between the digital document and the digital calendar event. In particular, one or more embodiments determine a content connection based on document characteristics (e.g., document content and access characteristics) and calendar event characteristics (e.g., calendar content and historical meeting information). For example, the system can train a machine learning model to determine content connections based on document characteristics and calendar event characteristics.

Abstract: A system, method, and computer program for enabling a user to edit and access local and remote objects via a virtual drive, including objects synchronized to a plurality of synchronization clients. A virtual drive is displayed on the user's local client device with all objects, which a user has synchronized to a synchronization server. A user is able to access and edit any object displayed in the virtual drive. In response to detecting a change in an object in the virtual drive, the object is updated on the synchronization server. All remote clients of the user or of any other users who have access to the changed folder are identified and notified of the change. In response to the change being a change to content within the folder, the content of the folder is automatically updated on any identified remote clients that have a corresponding folder.

Abstract: The present disclosure is directed toward systems, methods, and non-transitory computer readable media for generating and providing a collaborative content management interface for a group of users. For example, the systems described herein can detect user input to add a header within the collaborative content management interface. The systems can cause a file management system to generate a subfolder that corresponds with the new header in the collaborative content management interface. Conversely, the systems can analyze a file database maintained by a file management system and, in response to user input to initiate a collaborative content management system, generate a collaborative content management interface with graphical elements to represent files and headers to represent subfolders.

Abstract: Computer-implemented techniques for replication-lag constrained deletion of data in a distributed data storage system. In some aspects, the techniques improve the operation of a computing system by preventing too high of a delete rate that causes severe replication lag while at the same time increasing and decreasing the delete rate over time to a maximum allowable delete rate constrained by measured replication lag in terms of both local replication lag and geographic replication lag. In one implementation, the delete rate is adjusted by increasing or decreasing a pause interval that determines how long a database data deletion process pauses between submitting database deletion commands to a database server.

Abstract: 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.

Abstract: Computer-implemented techniques for sematic image retrieval. According to one technique, digital images are classified into N number of categories based on their visual content. The classification provides a set of N-dimensional image vectors for the digital images. Each image vector contains up to N number of probability values for up to N number of corresponding categories. An N-dimensional image match vector is generated that projects an input keyword query into the vector space of the set of image vectors by computing the vector similarities between a word vector for the input query and a word vector for each of the N number of categories. Vector similarities between the image match vectors and the set of image vectors can be computed to determine images semantically relevant to the input query.

Abstract: In some implementations, a user can be notified when a content item operation initiated by the user on a client device may render a shared or linked content item inaccessible to the user or others. The notification can give the user an option to undo the content item operation. In some implementations, movement of a content item from one directory location to another directory location can be recorded in entries of a local content journal. The local content journal entries can be shared with a content management system and other client devices so that the corresponding content items on the client devices can be moved without downloading additional copies of the content item to the client devices.

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 technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for providing access to a hybrid web application offline. In some implementations, a computing device can be configured with a hybrid application that includes a native layer and a web view. The native layer can provide access to native features of the computing device while the web view can provide web client features, such as graphical user interfaces and server communication functionality. When the computing device is offline and the hybrid application is invoked, the native layer can load from local storage a resource bundle including the web code needed to present the web view graphical user interface, and/or facilitate communication with the web server. Similarly, when the computing device is offline, the hybrid application can load previously stored content items into the web view from local storage through the native layer so that the user can work with the content items offline.
