Syntax

Parameter Set: Publish_BCFileHashes12
Publish-BCFileContent [-Path] <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-Force] [-Recurse] [-ReferenceFile <String> ] [-StageData] [-StagingPath <String> ] [-ThrottleLimit <Int32> ] [-UseVersion <UInt32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Publish-BCFileContent cmdlet generates hashes, also called content information, for files in shared folders on file servers that have BranchCache enabled and the BranchCache for Network Files role service installed.

This cmdlet is also used to stage data for the creation of a data preloading package. Run this cmdlet with the StageData parameter on one or more collections of files, then call the Export-BCCachePackage cmdlet to produce a data package containing all the staged data. This data package can be imported on remote hosted cache computers.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

If version specified is 2, then content information is generated according to the more efficient hashing scheme used by client computers that are running operating systems later than Windows 7.
