Organizing Fonts in Folders (A,B,C...)

Hello,
I?ve purchased a new cd with many many useful fonts. But I also have many of others in my computer.
To manage these fonts I use a very good program called Suitcase (from Extensis).
But now I want to organize these fonts that I have in my computer, each family in one folder.
What Im looking for is this: a program that Scan my pc a organize my fonts by letter and inside "letter folder", the family font folde.

Example
A/
B/
C/
D/
/Dax
Dax Medium.ttf
Dax Bold.ttf
Dax DemiBold.ttf
Dax Regular.ttf
/Dinn
/Doperlate
E/

Well... I already found a program that does it, but I dont know why the program (called Fontdoctor) cannot finish the process. Always appear a error.
So.. Im here looking for a help, is there similar programs? Could be shareware too. If I like, I propably will buy, its very useful and needed to me.

Thanks guys.
And sorry for this english
