hard drive capacity

[JOHN NORRIS]

i'm new to computers, and am loading cdg's in hoster. i just started to load and before i get too far, wanted input on whether or not to load onto external hard drive initially (and how to divert songs to it) or just load into laptop hard drive/ 100gb capacity on laptop/ 300 gb on external. i have about 15,000 songs to load 1/3 vcd's- 2/3 cdg's. need specific instruction to divert to external hard drive if it's necessary. thx- all previous help was a lifesaver
