Gets or sets whether the dialog box supports displaying and saving files that have multiple file name extensions.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Sometimes users must open and save files that use multiple file name extensions. For example, the application manifest files used by the ClickOnce deployment technology end in the complex file name extension ".exe.manifest". Setting this property to true enables you to set the Filter property to a multi-dotted extension.
If is false, and you assign a multi-dotted extension to Filter, derived controls such as SaveFileDialog will only use the last extension in the string. For example, ".manifest" will be used instead of ".exe.manifest".
