The way I have done it in the past is go to the folder of choice then SELECT one of UR SND files not any file (u can do so by going to FILES CHOICE, SOUNDS/PRGORAMS, SOUNDS), that should list ur SND files only.

Select the first one, with SELECT, then push SAVE/ENTER...go back to the main folder screen (exit then hit DISK again and select that folder). You should see the first file in the list be INIT00.PWR.

Now if u turn on the X1, those SND files in that folder should load automatically.
