	FilterFilesOnly	Gets or sets a value indicating whether the Filter property applies to files only, but all folders are listed.
	FilterRegularExpression	Define a regular expression to filter the files that will be enumerated.
	Folder	Use Folder to specify the path of the folder, which should be browsed or to get the path that is currently active.
	FolderIdList	This property should only be used by advanced users. The returned ItemIdList has to be freed when it is not needed any more.
	FullPath	Gets or set the full path of the active object.
	HasSubFolders	Checks if the currently active object has subfolders.
	IsEnumerable	True if the currently active object is a folder and can be browsed.
	IsFolder	Can be used to query if the currently active object is a folder or not.
	IsVistaOrLater	Returns true if the system runs the windows vista operating system or later.
	IsWindows10OrLater	Returns true if the system runs the Windows 10 operating system or later.
	IsWindows7OrLater	Returns true if the system runs the Windows 7 operating system or later.
	IsWindows8OrLater	Returns true if the system runs the Windows 8 operating system or later.
	IsXpOrLater	Returns true if the system runs the windows xp operating system or later.
	ItemIdList	Returns the relative ItemIdList of the current element in this instance.
	MultiObjects	Holds a list of files that serves as selection for some operations like showing the context menu.
	ObjectName	Use ObjectName to specify the current object or to retrieve the file system name of the current object. A valid folder must be set, see FullPath and SpecialFolder
	ShowErrorMessages	If set to to 'true', error messages will be shown to the user. If set to 'false', error messages will be suppressed.
