merging kma files

[pselph2528]

I will be installing hoster 3319 on a back up Computer (windows XP). I have appox 61,000 kma songs on an exteral hard drive that i use with my primary computer (also an XP with hoster 3319 installed). Can someone give me an easy step by step way to merge or install these songs thru the new, fresh 3319 so that i can use the same external hard drive on either computer?
After installing 3319 on my back up computer, will it as me to rebuild song data base since i will not have any songs on that hoster at that time?
Please make it as simple as possible, as i am not a computer wheez.
Thank you
Paul Selph
