Thanks. AppleSingle and AppleDouble are archival formats for the Apple II. They are designed to allow fully recoverable storage of files from other filesystems: filesystems that might have names illegal on the ProDOS filesystem, files which might be forked, etc. AppleSingle stores the entire file into the data fork of a file. AppleDouble uses two files: a header and a data file. For full documentation, read the File Type notes on these two formats; they're published by AIIDTS and available from most II archive sites. > Also, since I haven't tried this, what happens when you try to use > AFE to convert a forked file? Death? Or, does it say "Oh, I've got > a resource and a data fork here, I'll just put them in the right place." It ignores the resource fork altogether, treating as if it only had a data fork. If you're trying to translate from ProDOS to HFS, then you get an error when it tries to read from a storage type it doesn't recognize.
