Re: standard file extensions for exported apple dos files ?

howdy,

I'm playing with some code where it will be handy for me to have on a
modern file system (e.g. ntfs) some files exported from Apple DOS 3.3
disk images, but I'd like to retain the 'file type' metadata when I do
that.

More specifically, I want to recognise 1) that the files are Apple 2
files, and 2) differentiate between Binary files (with the first 4
bytes being load address and file length), Applesoft files, Text files
etc.

The only cross-platform place for storing file metadata is in the file
extension, but there doesn't seem to be any convention or standard
file extension used for this purpose - BIN and BAS are too generic.

I am considering using .?33, where the first char is the DOS 3.3 file
type (i.e. a binary file will get saved with extension .B33, an
Applesoft file will get .A33 etc).

But is anyone aware of unique extensions already being used for this
purpose?


These aren't common or standard by any means but I've used .PG2 for DOS 3.3 binary files for several years, and use .FP for Applesoft files.
