This method is more reliable than using environment variables as it works consistently across different Windows versions and language settings. Supports all standard Windows known folders like Documents, Downloads, AppData etc. .PARAMETER KnownFolder Specifies the name of the Windows known folder to retrieve. Must be one of the predefined folder names like 'Documents', 'Downloads', etc. The function will return the full path to this folder. .EXAMPLE Get-KnownFolderPath -KnownFolder 'Documents' Returns: C:\Users\Username\Documents .EXAMPLE folder Downloads Returns: C:\Users\Username\Downloads using the alias .EXAMPLE cd (folder Desktop) Changes to the Desktop folder using the alias #> function Get-KnownFolderPath { [CmdletBinding()] [Alias('folder')] param ( ######################################################################## [Parameter( Mandatory = $true, Position = 0, HelpMessage = 'The Windows known folder name to get the path for' )] [ValidateSet('3DObjects', 'AddNewPrograms', 'AdminTools', 'AppUpdates', 'CDBurning', 'ChangeRemovePrograms', 'CommonAdminTools', 'CommonOEMLinks', 'CommonPrograms', 'CommonStartMenu', 'CommonStartup', 'CommonTemplates', 'ComputerFolder', 'ConflictFolder', 'ConnectionsFolder', 'Contacts', 'ControlPanelFolder', 'Cookies', 'Desktop', 'Documents', 'Downloads', 'Favorites', 'Fonts', 'Games', 'GameTasks', 'History', 'InternetCache', 'InternetFolder', 'Links', 'LocalAppData', 'LocalAppDataLow', 'LocalizedResourcesDir', 'Music', 'NetHood', 'NetworkFolder', 'OriginalImages', 'PhotoAlbums', 'Pictures', 'Playlists', 'PrintersFolder', 'PrintHood', 'Profile', 'ProgramData', 'ProgramFiles', 'ProgramFilesX64', 'ProgramFilesX86', 'ProgramFilesCommon', 'ProgramFilesCommonX64', 'ProgramFilesCommonX86', 'Programs', 'Public', 'PublicDesktop', 'PublicDocuments', 'PublicDownloads', 'PublicGameTasks', 'PublicMusic', 'PublicPictures', 'PublicVideos', 'QuickLaunch', 'Recent', 'RecycleBinFolder', 'ResourceDir', 'RoamingAppData', 'SampleMusic', 'SamplePictures', 'SamplePlaylists', 'SampleVideos', 'SavedGames', 'SavedSearches', 'SEARCH_CSC', 'SEARCH_MAPI', 'SearchHome', 'SendTo', 'SidebarDefaultParts', 'SidebarParts', 'StartMenu', 'Startup', 'SyncManagerFolder', 'SyncResultsFolder', 'SyncSetupFolder', 'System', 'SystemX86', 'Templates', 'TreeProperties', 'UserProfiles', 'UsersFiles', 'Videos', 'Windows')] [string]$KnownFolder ######################################################################## ) begin { # define known folder guids for windows shell32 api $knownFolders = @{ '3DObjects' = '31C0DD25-9439-4F12-BF41-7FF4EDA38722';
