B.A.D. has a switch you set to either 'WB' or 'CLI', specifying whether
you want to have fast-appearing icons or rather fast-listing list'ings.
There is no doubt that it speeds icon appearance on the WB - click on a
Blitz'd disk and >whoosh< the icons appear with nary a gronk from the 
drive.  I believe it moves all the .info files to the same track
(whatever) so they can load without seeking all over the disk.

I am not sure about the data blocks of the files, however. I don't notice
any big difference in the time it takes to actually load a program.

Anybody know if B.A.D. twiddles with data blocks, or is it just
directories -or- .info files?
