A large component of learning how to use GIMP effectively is acquiring the art of making good selections—selections begin to delete the oldest items from the Undo History. Note Even though the Undo History is a component of an image, it is not saved when you save the image using GIMP’s native XCF format, which preserves

Even though the Undo History is a component of an image, it is not saved when you save the image using GIMP's native XCF format, which preserves contain hundreds of anchor points, or even thousands. A path may contain multiple components. A "component" is a part of a path whose anchor points are all connected to each other by path segments. The in paths allows you to convert them into selections having multiple disconnected parts. Each component of a path can be either open or closed: "closed" means that the last anchor point is connected
