Description

The New-SmbShare cmdlet exposes a file system folder to remote clients as a Server Message Block (SMB) share.

To delete a share that was created by this cmdlet, use the Remove-SmbShare cmdlet.

Examples

Example 1: Create an SMB share

$Parameters = @{
    Name = 'VMSFiles'
    Path = 'C:\ClusterStorage\Volume1\VMFiles'
    FullAccess = 'Contoso\Administrator', 'Contoso\Contoso-HV1$'
}
New-SmbShare @Parameters

This command creates an SMB share named VMSFiles and grants Full Access permissions to Contoso\Administrator, and Contoso\Contoso-HV1$.

This example uses splatting to pass parameter values from the $Parameters variable to the command. Learn more about Splatting.

Example 2: Create an encrypted SMB share

New-SmbShare -Name "Data" -Path "J:\Data" -EncryptData $True

This command creates an encrypted SMB share.

Example 3: Create an SMB share with Multiple Permissions

$Parameters = @{
    Name = 'VMSFiles'
    Path = 'C:\ClusterStorage\Volume1\VMFiles'
    ChangeAccess = 'CONTOSO\Finance Users','CONTOSO\HR Users'
    FullAccess = 'Administrators'
}
New-SmbShare @Parameters

This command creates an SMB share named VMSFiles and grants Change permissions to the domain groups CONTOSO\Finance Users and CONTOSO\HR Users. Full Access permissions to the builtin Administrators group.

This example uses splatting to pass parameter values from the $Parameters variable to the command. Learn more about Splatting.

Outputs

CimInstance

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object. This cmdlet returns a MSFT_SmbShare object that represents the SMB share.
