Can't delete folders. response is devise not responding
to delete files there are 2 ways to do this.(1) first is with the on and facing you. on top the is the black menu switch. (2)hold down until it reads play music,and release (3) cycle either way until it reads delete.(4) cycle the switch until it reads del / push switch in (5) cycle to voice (6) push switch in to delete files. (cycle to exit and push switch again it should go to your music.
Second way is to plug it into a computer with plug and play.with the Trio MP3 on, the computer should open up a menu, chose open files (2) the screen should have music, voice and other files on the display. chose the voice file and click it open. use the mouse to delete files / or point and use the key board delete key to delete files. IF PLUG and Play does not open up goto MY Computer and openit up. drop down to the removeable disk and click open. you should be where you can delete the voice file. good luck and have fun.
