EXS 24 Logic Sampler Users Group

hi there! i know it's kinda old questin but, i have some samplecell original cds and woul like 
to convert them to exs, but as they don t have any extension the mac os x reads them as unix 
files, you know when they stay without any icon, greyish?
do u have a step by step process for that?
than a lot again
