EXS 24 Logic Sampler Users Group

I recently bought a bargain DVD of Gigastudio files on eBay, so cheap
that I can happily discard any turkeys. I have an external USB 2.0
drive for sample storage, which is where I keep all the factory
samples and my own stuff . I copied the *.gig files into a separate
folder on this drive, with an alias in the Sampler Instruments folder
on the main drive. There is no problem with EXS24 recognising  most of
the *.gig files and doing its conversion thing, but what it is doing
with the folders of samples it creates is saving them in a folder
called DLS-Giga Samples in the Logic folder in Application Support,
while saving the Sampler Instruments in the source folder on the
external drive. This wouldn't be a problem if I could actually access
this folder to organise the
samples, but though I can search for the individual samples and see
the file path for them, no amount of tinkering with permissions will
show the folder in the finder. I also can't access any new sampler
instruments or folders I have created for them via the EXS24 save
dialogue box.

Is there something I have missed here? I'm pretty new to OS X, though
I'm an old Logic hand. I'm running the latest Logic and the latest
update to Tiger on a Mac Mini. I have searched for relevant posts
here, but while there was something about a freeware app called
batchmod, which I have tried, it didn't solve the problem. In the
