Slight correction: the "Resource Fork" was (and is) an alternate data stream, a term familiar from NTFS. Apple did keep Finder Info (including the file's attributes such as visibility and application information such as type and creator codes) and some other metadata in the file's catalog entry. It was stored separately on other more limited filesystems, often in an AppleDouble file, or it could be stored with the data in an AppleSingle file. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
