I've got my old 3.9 bb2 installation running again. It's on a 8GB microdrive that has multiple partitions.
One of the partitions contains a LOT of folders with WHDLoad games, each folder has a game in it. When I open this partition in workbench it takes a few minutes before the listing shows. In the meantime I can't do anything else.
This partition is either in FFS of SFS, I don't quite remember, but it takes so long. Is there a way to speed up the directory listing?
I remember from older installations there was a .fastdir file that contained the listing? Never seen that on 3.9 though.
Sorry if someone's already mentioned this (not read the full thread) but why not use a WHDLoad front-end rather than launching them all from Workbench?
I just have the excellent, and very simple to use iGame in my dock and load all the games from that in a few seconds:
