Aspects of the subject matter described herein relate to file system placeholders. In aspects, placeholders may be used by a client to represent remote file system objects. The placeholders may include metadata and may also include none, some, or all of the content of the represented remote file system objects. In response to a request to access content of a file system object represented by a placeholder, a client may obtain needed data from a remote storage system and stream or not stream the data to the requesting application based on whether the requesting application is capable of streaming the data.

Streaming content and placeholders

Metered network synchronization techniques are described. A current network connection of a computing device is checked as to whether the current network connection has been identified as a metered network. Access by a synchronization engine of the computing device to communicate via the current network connection to synchronize data of the computing device with another computing device is managed based at least in part on a setting associated with the metered network.

Metered network synchronization

In one embodiment, a user device may store state data for an application at an internet-accessible data storagefor access by other devices of the user. The target user devicemay use an untrusted platformto generate an access requestfor an application state data set for a source application. The target user devicemay send the access requestto the internet-accessible data storage. The target user devicemay send an access credentialto the internet-accessible data storage

Roaming internet-accessible application state across trusted and untrusted platforms

Aspects of the subject matter described herein relate to file system placeholders. In aspects, placeholders may be used by a client to represent remote file system objects. The placeholders may include metadata, searchable text, and may also include none, some, or all of the content of the represented remote file system objects. Search data from the placeholders is integrated into a local search database of the client such that the client is able to satisfy queries and identify relevant local and remote file system objects even when the client is offline with respect to remote storage.

Searching and placeholders

Aspects of the subject matter described herein relate to file system placeholders. In aspects, placeholders may be used by a client to represent remote file system objects. The placeholders may include metadata and may also include none, some, or all of the content of the represented remote file system objects. In conjunction with local file system metadata, the placeholders allow a file system namespace to be navigated and may also allow other operations to be performed on the file system objects even when the client is offline with respect to the remote file system. After connectivity is re-established with the remote file system, the placeholders may be used in synchronizing changes.

File management with placeholders

Techniques for data synchronization policies are described. In one or more implementations, techniques may be employed to set data synchronization ('sync') policies for devices in a data sync environment. The sync policies specify parameters for sync operations in the sync environment, such as how frequently data sync operations are performed, what types of data are synced to particular devices, how frequently particular types of data are synced, and so on. In implementations, the sync policies consider the number of devices that are participating in a sync environment and attributes of the devices in specifying parameters for sync operations. Data can be synchronized among devices in the sync environment based on the sync policies.

Data synchronization policies

Embodiments described herein may involve enabling applications to cooperate with a system-level sync framework. The sync framework may provide system synchronization of files between user devices and a cloud storage service. Arbitrary applications on a user computing device can communicate with the sync framework to temporarily suspend synchronization of a specified file by the sync framework. The application can register functions with the sync framework that the sync framework can invoke in relation to suspending synchronization, continuing to provide system-level access to the file for arbitrary applications, and resuming synchronization.

Sync framework extensibility

Aspects of the subject matter described herein relate to file system placeholders. In aspects, placeholders may be used by a client to represent remote file system objects. The placeholders may include metadata and may also include none, some, or all of the content of the represented remote file system objects. In conjunction with placeholders and based on one or more factors, a client may hydrate or dehydrate file system objects of the client to follow user directives, inferred user intent, and storage policies of the client.
