Wow! I wish. :-) Assuming you mean 686208 _bytes_, it will fit into 686208 bytes plus any overhead required. If you are using RAM: (not RAM), there is some overhead required for the name of the file, some pointers to it, and pointers to other entries in RAM: >I turn on my 1 meg A500 with a boot disk in it and hit ctrl-d.
