Problems with "favourites.dat"

I am attempting to use SmartFTP on a USB pen drive, so that I can use it on multiple computers without installing it on each of them. However, I have a little problem. Each time I run SmartFTP from the pen drive, it requires "favourites.dat" from the local (C:) drive. Is there a way to change where the program writes/reads "favourites.dat"?



Thanks
