#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# 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 The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER DatabaseCollection Internal Variable .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 Author: Stuart Moore (@napalmgram), stuart-moore.com Tags: Database
