When Exporting how to make Textures TGA?

Hey Guys I am extremely new to Blender.
I exported a Model earlier that I also textured using Blender tools. How would i go about having these textures save out as a TGA file?

Blender can export images using the “Targa” format, which is, literally speaking, a TGA file.

Now where and how exactly youre exporting this image, no idea, so I couldnt say if you can use this or not… Hope this is helpful
