Actually, i tried to make my life easier. I am not good in maintaining documentation of my project. So with long file name, I can easily spot the file i need...
I like to name them this way:
dialer_mt8888.asm
dialer_tp5088.asm
dialer_mt_8880.asm
which give me snap shot of what hardware i use... and I can go eazy with my life :)

... and look, I've been avoiding "spaces" !
