"Personally, I use NCH Express Burn and individually load each .wav file or .mp3 file in the order that I want them burned. No mistakes that way." I've been trying this but with no success. When I try to add the split files using Express Burn, I can't get to them. The split files are stored in app data>roaming>NCH Swift Sound>Golden. However, when I try to open that location from Express Burn>Add Files, I cannot. This is where I get stopped: app data>roaming>microsoft. There's a microsoft folder with subfolders, but there's not an NCH Swift Sound folder.
