BITS interfaces

Use the following Background Intelligent Transfer Service (BITS) interfaces to transfer files and monitor jobs within the transfer queue.

Interface	Description
IBackgroundCopyCallback	Clients implement the IBackgroundCopyCallback interface to receive notification that a job is complete, has been modified, or is in error.
IBackgroundCopyCallback2	Clients implement the IBackgroundCopyCallback2 interface to receive notification that a file has completed downloading.
IBackgroundCopyCallback3	Clients implement the IBackgroundCopyCallback3 interface to receive notification that ranges of a file have completed downloading.
IBackgroundCopyError	Retrieves details of a job error.
IBackgroundCopyFile	Retrieves the local and remote file names of a file transfer request in the job and its progress.
IBackgroundCopyFile2	Specifies a new remote name for the file and retrieves the list of ranges to download.
IBackgroundCopyFile3	Validates the file so that peers can request its content and retrieves the name of the temporary file.
IBackgroundCopyFile4	Retrieves download statistics for peers and origin servers.
IBackgroundCopyFile5	Provides generic property get and set methods for BackgroundCopyFile properties.
IBackgroundCopyFile6	Gets or sets generic properties of BITS file transfers.
IBackgroundCopyJob	Adds files to the job, sets the priority level of the job, determines the state of the job, and starts and stops the job.
IBackgroundCopyJob2	Retrieves reply data from an upload job, determines the progress of the reply data transfer to the client, requests command line execution, and provides credentials for a proxy and remote server.
IBackgroundCopyJob3	Downloads ranges of a file, changes the prefix of a remote file name, and maintains the owner and ACL information with the file.
IBackgroundCopyJob4	Enables peer caching, restrict download time, and inspect user token characteristics.
IBackgroundCopyJob5	Queries or sets several optional behaviors of a job.
IBackgroundCopyJobHttpOptions	Specifies client certificates for certificate-based client authentication and custom headers for HTTP requests.
IBackgroundCopyJobHttpOptions2	Use this interface to retrieve and/or to override the HTTP method used for a BITS transfer.
IBackgroundCopyManager	Creates transfer jobs, retrieves an enumerator object of jobs in the queue, and retrieves individual jobs from the queue.
IBitsPeer	Gets information about a peer in the neighborhood.
IBitsPeerCacheAdministration	Manage the pool of peers from which you can download content.
IBitsPeerCacheRecord	Gets information about a file in the cache.
IBitsTokenOptions	Associates and manages a pair of security tokens for a Background Intelligent Transfer Service (BITS) transfer job.
IEnumBackgroundCopyFiles	Enumerates files in the job.
IEnumBackgroundCopyJobs	Enumerates jobs in the transfer queue.
IEnumBitsPeerCacheRecords	Enumerates the records of the cache.
IEnumBitsPeers	Enumerates the list of peers that BITS has discovered.
