Emotion Sounds for Plus are stored in C:\Documents and Settings\All Users\Application Data\Messenger Plus!\Custom Sounds. For Vista this should be something like C:\Users\All Users\AppData\Messenger Plus!\Custom Sounds. There should be some .dat files in the folder; these are just renamed .mp3 files. To identify which sound is which, simply open the Sound Library, select a sound, click Edit, and look at its Internal Sound Identifier.
