Apple II File Type Notes _____________________________________________________________________________ Developer Technical Support File Type: $00 (0) Auxiliary Type: All Full Name: Typeless file Short Name: Unknown Written by: Matt Deatherage March 1990 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.
