-They both work very similar, starting with a file dialog to choose which file to import and then turning this file into a graph and adding it. The only difference is that 'Insert File' adds the loaded graph to the root of the scene and 'Insert File to RGG' to the RGG root. This leads to the difference that a file inserted to RGG will be removed when the model is rested or recompiled. +They both work very similar, starting with a file dialog to choose which file to import and then turning this file into a graph and adding it.

-__Embed the file:__ The file is read and added to the meta Graph.
