My company makes a software program that runs on both Windows and Mac. While the main program executable and a few other files are different for the Windows version vs. the Mac version, the vast majority of the files are the same. I'd therefore like to be able to provide a single download that has all the files necessary for both Mac and Windows. But I'd like the Mac-only files to be hidden on Windows, and the Windows-only files to be hidden on Mac.
Is this possible, and if so, how?
