OK so far. > Then MacOS drops the resource fork when copying to ProDOS. Not exactly. If the filetype and creator have been set to a recognised ProDOS combination (or the file is type 'TEXT' with any creator), AND the file has a zero length resource fork, then the file will end up being a standard file when copied to a ProDOS volume, and will be accessible from ProDOS-8. If the file type or creator can't be represented in ProDOS, or if the file already has a resource fork, then the file will end up being an extended file when copied to a ProDOS volume, and will only be accessible from GS/OS (or the Mac). An extended file on a ProDOS volume doesn't necessarily have a resource fork: it might just have a single extra block (the "extended key block"), which contains the extra Macintosh directory information, including the Mac file type and creator. ProType ensures that the file type and creator obey ProDOS rules, but it doesn't do anything about an already existing resource fork. -- David Empson dempson@actrix.gen.nz Snail mail: P O Box 27-103, Wellington, New Zealand
