I do not own or have acess to a computer. But. Have been introduced to the ASTRO app found in the market. From there you can move files and such. Anyway, i move all my ringtones to the zedge file so when I choose sms ringtone from setings all my ringtones will be in zedge, which is one of the options to choose from. Sry my computer lingo isn't very detailed , none the less I hope. This helps.
