What is it, and how is it used? Thanks, Milt.
Macintosh OS-X disk image format. If on Windows and you need to, you can actually access the contents using for example the 7zip program.
Thanks, Xenakios, I thought it was some kind of image file, but I had never had to use one for Reaper to function properly. As I am on Windows, no need to download it. Thanks again, Milt.
