OSX uses the 3 digit extensions, as I understand the Apple II does.
But the standard Mac OS does not.
The Apple II doesn't normally use filename extensions, it stores the
file type in the directory like the Mac OS traditionally does. However,
these get lost easily when a file is transferred via a non-Apple system
like a PC disk or the Interent, so filename extensions are often added.
On the IIgs it is possible to make a Finder icon file which matches by
name or by file type. For instance, ShrinkIt has an icon file which
matches files which end in .shk or .sdk, or files with a type of $E0/
$8002 no matter what their name is, so the Finder knows that these files belong to ShrinkIt, even if they don't have the file type set properly.
On the Mac however, before OS X, there is no way to match a filename
extension to a file type in the Mac Finder. When a file is copied from a
PC disk it's up to PC Exchange to look at the filename extension and
give the file the correct file type, and when a file is downloaded
Internat Config does the same thing, but the Finder itself can't do it.
Does one need to rename mac files
to 3 digit extensions when giving an OSX user a floppy or other
removable disk?
Some files you just do not know the extensions. Will they open fine
under OSX?
There is no need to rename them for OS X. In OS X the Finder first uses
the file type stored in the directory, and if it doesn't exist it then
uses any filename extension.
