Q: I used to be able to open a PAWriter data file in PAWriter by just double clicking on the data file icon. Now if I send the file to someone else they can't open the file in Snow Leopard. What do I do now?
A: In this case, the hidden Type and Creator codes in a PAWriter data file are no longer used to launch PAWriter, as they did in every previous MacOS including MacOS 9 and earlier systems. Now the extension .paw must appear at the end of the data file's name.
If you really want to know more about the technical reasons and details for this change in the MacOS, please see:
As noted therein, "Apple didn't schedule a deprecation of Creator Codes just for fun, or just to be lazy, or just to fit in with lowest common denominator operating systems. Type and Creator Codes simply weren't good enough to support new OS features Apple had on the drawing board. Rather than trying to get by with doing less, Apple was set on doing more, and Creator Codes weren't up to the task."
To help with this, in version 97 and later the extension .paw will be added to new files (initially labeled "Untitled") when they are first saved.
