- Files of this type and auxiliary type contain data that is unknown to the
- file's creator.
- _____________________________________________________________________________
-
- Files of type $00 contain data that is unknown to the program that creates the
- file. There are instances where programs, especially utilities, have to
- create files before they know the eventual file type and auxiliary type of the
- file. A good example of this is a telecommunications program that downloads a
- file without a Binary II or other header to preserve the file's attributes.
- Not knowing the file type, the program has little choice but to assign the
- file as an "unknown" type until such time as the real file type can be
- determined or assigned.
-
- Files should be given type $00 when the creating program cannot determine the
- real file type. Reasonable guesses can be made (to continue the above
- example, a telecommunications program might assign file type $04 for all files
- transferred without protocol, guessing that ASCII transfers are probably for
- ASCII Text files).
-
- File type $00 is not to be used for files regularly used by applications
- simply because the application programmer didn't wish to obtain a file type
- and auxiliary type assignment.
-
- The auxiliary types for this file type are reserved; any files created of type
- $00 should be created with auxiliary type $0000.
