Palettes are stored as files with .Pal (palette) extensions.

Be aware that saving a palette and then applying it to another image using Palette Menu > Select Palette Menu > Load Palette may not give you the results you are expecting.

This is because when you create a palette you normally go through several steps of palette reduction and adjustment before arriving at that palette. But when you load a palette the colors on the image are mapped directly to the colors on the palette without intermediate steps. Because the methods of arriving at the palette are different, the effects are likely to be different.
