Actually, he's right. In 10.6 the content of very small files are stuffed into the HFS attributes file. They're referred to as "named forks", but they're stored inline with attributes, and do not have any blocks allocated for data storage. Many system files too large to be stored as an attribute in the attributes file do have their compressed content stored in a resource fork, which does have a distinct allocation of blocks for its storage--and I guess that's what you're thinking of. -- Scott Ribe [email protected] http://www.elevated-dev.com/ (303) 722-0567 voice _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
