All we need os a ftp with lots of server space

They arent any way to make them faster, since it uses CPU power.
Now I have another question

I've made the alpha tabels, and testet them. Now are there any way to "upgrade" them to alpha-numeric without having to regenerat all the tabels again? maybe by just generating the missing tabels, and then import them into the old ones.
What i mean is, I already have aa, ab, ac hashs.. but not hashs with numbers in it ie. a1, a2, a3, jehh3ks, 83kk233
are there any way to generat a tabel with the new number hashs, then import the new tabel to the old one, and resort

maybe by the "copy /b" command?
Hope you got the picture
