function Get-DbaFile { <# .SYNOPSIS Get-DbaFile finds files in any directory specified on a remote SQL Server .DESCRIPTION This command searches all specified directories, allowing a DBA to see file information on a server without direct access You can filter by extension using the -FileType parameter. By default, the default data directory will be returned. You can provide and additional paths to search using the -Path parameter. Thanks to serg-52 for the query: https://www.sqlservercentral.com/Forums/Topic1642213-391-1.aspx .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Allows you to login to servers using alternative credentials .PARAMETER Path Used to specify extra directories to search in addition to the default data directory. .PARAMETER FileType Used to specify filter by filetype. No dot required, just pass the extension. .PARAMETER Depth Used to specify recursive folder depth. Default is 1, non-recursive. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Discovery Author: Brandon Abshire, netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaFile .EXAMPLE PS C:\> Get-DbaFile -SqlInstance sqlserver2014a -Path E:\Dir1 Logs into the SQL Server "sqlserver2014a" using Windows credentials and searches E:\Dir for all files .EXAMPLE PS C:\> Get-DbaFile -SqlInstance sqlserver2014a -SqlCredential $cred -Path 'E:\sql files' Logs into the SQL Server "sqlserver2014a" using alternative credentials and returns all files in 'E:\sql files' .EXAMPLE PS C:\> $all = Get-DbaDefaultPath -SqlInstance sql2014 PS C:\> Get-DbaFile -SqlInstance sql2014 -Path $all.Data, $all.Log, $all.Backup -Depth 3 Returns the files in the default data, log and backup directories on sql2014, 3 directories deep (recursively). .EXAMPLE PS C:\> Get-DbaFile -SqlInstance sql2014 -Path 'E:\Dir1', 'E:\Dir2' Returns the files in "E:\Dir1" and "E:Dir2" on sql2014 .EXAMPLE PS C:\> Get-DbaFile -SqlInstance sql2014, sql2016 -Path 'E:\Dir1' -FileType fsf, mld Finds files in E:\Dir1 ending with ".fsf" and ".mld" for both the servers sql2014 and sql2016. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$Path, [string[]]$FileType, [int]$Depth = 1, [Alias('Silent')] [switch]$EnableException ) begin { $sql = "" function Get-SQLDirTreeQuery { param ( $PathList ) $q1 += "DECLARE @myPath nvarchar(4000);
