Function Get-DbaDatabaseFile { <# .SYNOPSIS Returns detailed information about database files. .DESCRIPTION Returns detailed information about database files. Does not use SMO - SMO causes enumeration and this command avoids that. .PARAMETER SqlInstance The target SQL Server instance(s) .PARAMETER SqlCredential Credentials to connect to the SQL Server instance if the calling user doesn't have permission .PARAMETER Database Name of the Databases to be scanned for file details. If left blank, will return for all accesible databases on the specified instance .PARAMETER DatabaseCollection Internal Variable .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Author: Stuart Moore (@napalmgram), stuart-moore.com Tags: Database Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .EXAMPLE Get-DbaDatabaseFile -SqlInstance sql2016 Will return an object containing all filegroups and their contained files for every database on the sql2016 SQL Server instance .EXAMPLE Get-DbaDatabaseFile -SqlInstance sql2016 -Database Impromptu Will return an object containing all filegroups and their contained files for the Impromptu Database on the sql2016 SQL Server instance .EXAMPLE Get-DbaDatabaseFile -SqlInstance sql2016 -Database Impromptu, Trading Will return an object containing all filegroups and their contained files for the Impromptu and Trading databases on the sql2016 SQL Server instance #> [CmdletBinding(DefaultParameterSetName = "Default")] param ( [parameter(ParameterSetName = "Pipe", Mandatory, ValueFromPipeline)] [object[]]$SqlInstance, [System.Management.Automation.PSCredential]$SqlCredential, [object[]]$DatabaseCollection, [switch]$Silent ) dynamicparam { if ($SqlInstance) { return Get-ParamSqlDatabases -SqlServer $SqlInstance[0] -SqlCredential $SqlCredential } } begin { $databases = $psboundparameters.Databases } process { foreach ($instance in $sqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlServer -SqlServer $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Failed to connect to $instance.
