If you have lots of soundfonts loaded in your Soundfont Bank and you're not sure of the exact name of a Soundfont  ("UserBank" is not very helpful)  or which Folder the Soundfont is in, here's one way to find out.

Go to Start Menu >  Run > regedit (type it in) > OK > (this takes you to the Registry Editor)
> HKEY_LOCAL_MACHINE (expand it by clicking the little plus sign) > Software (expand it ) > Soundfont (expand it ) > Files (expand it ) > 0 (expand it ) > then each of the folders has a number which corresponds to a Soundfont layer. 
Open the folder of the Soundfont layer you wish to find out about, and when you get to the last folder inside and highlight it, then on the right hand side of the screen it will show you the exact path and name of the Soundfont in that layer. 

And if there's a simpler way, please let me know at gort@callnetuk.com.
