<div dir="auto">My recollection from the 1980s when I worked with Apple and Windows software, is that Microsoft file names had 3-letter extensions following a dot, such as .txt or .pdf Whereas classic Macintosh files consisted of two parts: a data
fork and a resource fork. The resource fork included information that would identify the application to be called in order to process the contents of the data fork. So information about whether the file contents should be processed by an application that
interprets data in Portable Document Format wouldnt depend on a three-letter extension in the file name but rather on a pertinent entry in the resource fork </div>
<div dir="auto"><br>
</div>
<div dir="auto">I don't know how the efforts by Apple to facilitate compatibility with Microsoft files have evolved. But I'd be surprised if Apple's OS today happens to give particular significance to the capitalization of a 3- or 4-character string at the
end of a file name. Is anyone on this listserv familiar with the current state of Apple file structure?</div>
