Yes, save INTERNALLY is comfortable, but the file size sometimes become absurd but is really handy when you need to exchange your file with someone else (a good feature that not all the 3d software have), my 2 cent advice is to create a folder with all your textures and your 3d files or better than all, complete your 3d work, save a scene with INTERNALLY then open again the file and save it all EXTERNALLY in your folder, so you will have a copy of all your textures:-P -TOXE
