Dear Apple II Developer:

Please find enclosed the form for a requested File Type and Auxiliary Type 
assignment for Apple II computers.  Because the number of file types is 
severely limited (256 total), Apple Computer defines file types as generic 
descriptions of file contents and assigns specific auxiliary types to 
individual developers for specific file formats.  These combinations must be 
assigned by Apple, not solely arbitrated, due to the specialized assignment 
nature of generic file type descriptions.

Please copy the form and use it to request all file type and auxiliary type 
assignments.

The following pointers may assist you and prevent delays when requesting an 
assignment:

  o  You may use previously documented file formats without obtaining an 
     assignment for them (for example, you do not have to request an 
     assignment for text files, Apple Preferred graphics files or Audio IFF 
     sound files).

  o  You may use file types $F1 through $F8 at your convenience.  Apple does 
     not and will not arbitrate or document the use of these files.

  o  You should request an assignment if you create new file formats that you 
     wish to identify from a directory entry.  For example, text files are 
     identified by a file type of $04.  If you wish to be able to identify 
     your files similarly, you should request an assignment.

  o  Many programs identify files only by file type and not by auxiliary 
     type.  These programs only identify your files by the general category 
     of the file type, so it is important that we assign the best-suited type 
     to your files.  Please be as specific as possible in the "Generic type 
     of data in file" field so we don't have to ask you for more information. 

  o  All fields on the form are required and must not be left blank.  If you 
     cannot fill out a field (for example, your program doesn't have a final 
     name yet), please use temporary file types and auxiliary types in file 
     types $F1 through $F8 until all the information is available.  If 
     requesting multiple assignments, you may leave the address, technical 
     contact and telephone number lines blank as long as the forms are 
     attached to each other and one of them has all the fields completed.

  o  We can accommodate multiple requests (several combinations for one 
     program), but we cannot accommodate requests where the auxiliary type 
     field has been used as a field of flags.  Only Apple Computer, Inc. can 
     make such assignments, and then only for files that are system-wide and 
     not specific to a particular application.

  o  When your application ships using your assignment, tell us.  Otherwise 
     we do not publish or acknowledge the assignment in any way to the world 
     at large, and it is not included in the system software.  We do not wish 
     to pre-announce anyone's software.

  o  Please use a separate form for each requested file type and auxiliary 
     type assignment.

If you can, we would appreciate the file format so we can publish it in an 
Apple II File Type Note.  More information can be found in "About File Type 
Notes".  If you have further questions, please feel free to contact us at the 
address on the registration form.

Thank you,

Apple Computer, Inc.
