hi! i just want to ask..after rooting and installing custom rom on my cell phone, is it ok to transfer all the files of my sd card to another lager capacity sdcard and use it.. i'm sorry if this one already post here, but im trying to find any ans but i found none... thanks in advance...

another question, what is the use of busybox? i already installed custom rom(floyo 0.2), but it does not require me to install that busy box.. thanks in advance..
