EXS 24 Logic Sampler Users Group

Over the course of 18 months of not working with a particular set of samples 
and some careless `housecleaning' on my HD, some of my EXS24 
instruments can no longer find their samples. These all seem to be from one 
set: GIGA. The instruments are intact, with the original sample zones, 
layerings, key range, octave settings (...etc.) I set up a year and a half ago, but 
now, as I say, most of the samples can't be found. I SEE them ALL in a 
partition on my HD; most likely they were moved in one massive, ignorant 
clump  -in a fleeting moment of madness- months ago, when I wasn't thinking 
about the consequences of such an action. 
Now I've chosen to return to these instruments, but when I reload each 
missing sample, some of the instrument settings change, and I'm faced with 
reconfiguring all the instruments manually… all the layers on several keys per 
instrument… and there are a LOT of instruments. 

I have 2 questions to anyone who is out there: 

1) Is there an easy way to facilitate each instrument finding the new location of 
each requisite audio file… or are there any tricks anyone can suggest that 
would make this operation less time consuming? Is there any way –for 
example- that I can point an instrument to a folder to re-find an initial sample, 
and then have that instrument look to that same folder to fill out all the 
subsequent sample positions? 
2) When a missing sample IS re-found and re-loaded manually, what settings 
DO change on the EXS24 instrument, and is their an easy, seamless way to 
`show' the instrument the new location of the sample?

While I understand that the problem is simple: each instrument has it's own 
set of instructions as to where each of it's samples resides, in my case, it may 
well be that the samples are organized into the same subfolders... it's just that 
I've probably `organized' them by putting them into a new 'GIGA' sample 
folder… it will be irritating to have to manually reconfigure 2000+ samples. 

Does anyone have any ideas?

I use Logic 6.3.3.on a Mac G4 with 1G Ram.
