Methods, systems, and computer readable media for content item purging are provided. A contact item purger, such as may be incorporated within a local client application of a content management system running on a user device, may leverage knowledge as to which items have been uploaded to the content management system, and how long such content items have been stored on the user device, to propose items for deletion from the user device so as to reclaim storage space. A contact item purger may run on one or more user devices, and may activate upon various triggering events, based on various conditions and parameters, with or without user interaction, thus maintaining available memory capacity at all times.

Using a unique identifier from an electronic device to automatically create a limited-functionality account upon a predetermined event. Basing the limitations on the unique identifier that was used to create the limited-functionality account. Removing the limitations placed on a limited-functionality account upon the user of the account providing credentials adequate for the synchronized content management system to be able to enforce various policies.

Limited-functionality accounts

Techniques for cross-application content item management. In one embodiment, for example, a method comprises detecting a touch gesture related to a representation of a content item displayed by a first application. And based at least in part on detecting the touch gesture, a different application performing a content management action on the content item. The content management action may encompass storing the content item in a content item collection, sharing the content item with a user account, uploading the content item to a server, or a combination thereof.

Cross-application content item management

System and method for group participation in a digital media presentation are provided that are capable of selecting digital media items for inclusion in the presentation from multiple participant's accounts thereby creating a group presentation in which digital media items of each participant are included in the presentation. Selections of digital media items for inclusion in the presentation can be made directly at the direction of the participations or inferentially according to a selection algorithm. Selections can be made during the presentation thereby allowing a participant to join the presentation after it has started and contribute digital media items to the presentation while it is running.

Predicting what content items a user finds important and sending those items to a cache on the user's device at times when doing so will not drain resources and will not result in expensive data rates. Applying a ranking function that examines recency and other content metadata associated with the user's content items stored in a synchronized content management system. Determining how much of a ranked list of content items to cache and deciding when is a good time to send content items to the local cache.

Predictive caching and fetch priority

Embodiments are provided for using heuristics for selecting and saving content to a synced online content management system. In some embodiments, one or more content items and/or indices thereto may be received within a first application. For example, a user may receive a photograph within a text message application. In some embodiments, a first defined gesture may be detected by a user device and in response, a second application may open. In some embodiments, a second defined gesture may be detected, and in response a (a) store, (b) share, and/or (c) an assign to a collection, operation may be performed within the second application. Alternatively, these operations may be performed within the second application based on at least one predefined rule (without a second gesture required).

Heuristics for selecting and saving content to a synced online content management system

Methods, systems, and computer readable media for content item purging functionality are provided. A contact item purger, such as may be incorporated within a local client application of a content management system, leverages its knowledge as to which items have been uploaded to the content management system, and how long content items have been stored on the user device, to propose items for local deletion and thus reclaiming storage on the user device. A contact item purger may run on one or more devices of a user associated with an account on a content management system upon various triggering events, and may run with or without user interaction, thus maintaining available user device memory capacity at all times.
