It all comes down in the end to ther range of choices offered to users:

To wit: Digital Performer appends an ".L" or ".R" to files that represent the left and right channels of a stereo pair. Running these through your software (which would presumably insist on adding an extension) would make Digital Performer unable to recognize these files as the left and right channels of a pair.

So there remains the need to be able to create files without extensions, and therefore _with_ file types.



Interesting. .L and .R are extensions, so I guess that does not conflict with the guidelines! Looks like type/creator info can only describe so much, and thereafter extensions are surprisingly useful - and this from a major Mac software house. I don't have DP: is this approach confined to SD2 files, or is it used with AIFF/WAVE formats too? How does it label channels of a quad file? Are users permitted to change this convention? I notice that the Apple-bundled app "Sound Studio" has this option, but users are left to devise their own names for the two channels, and on importing Dual Mono are free to select any pair of sd2 files they fancy; so is .L and .R a SD2 convention, or a DP convention?


There is of course no technical impediment any more to using multiple dot-separated extensions: sfilename.L.sd2. It is simply a matter of defining the convention.

And as far as I can see, there is no technical impediment to supporting both Type/Creator and extensions when creating files: Audacity manages this very well, all with a single Save dialog, though no doubt further enhancements can yet be made. It is a cross-platform app however, and also free, both of which may make it invalid in the eyes of committed Mac users :-).

Far be from me to presume to challenge the status quo, but why do people think that somehow offering the user the extended choice of filename paradigm is so problematic? These would seem to be the choices for loading:

Type/Creator plus format extension (hidden or visible)
Type/Creator no extension
Plain file + extension


And for saving:

Type/Creator plus hidden format extension
Type/Creator plus visible format extension
Type/Creator no format extension (for backwards compatibility: the only pattern deprecated in the guidelines)

All this needs is a control in the Save dialog (or alternatively buried in Preferences) and users can save a file with exactly the naming protocol they want, even adding .L and .R etc if they like. There is no suggestion here of discarding the Type/Creator system, merely of adding support for extensions. And it is the not so subtle hostility to file extensions that surprises me, even though they do not threaten the established hegemony of Type/Creator in any way. Is it perhaps more of a "moral" issue than a mere technical one? Do format extensions not sit well with "thinking differently"? Is it really that users don't like them, or that users shouldn't like them?
