This only applies if you use the Direct Download option from your download page. If you use the Sonokinetic Content Manager to download and extract your purchased product, the process will be automated, leaving you with a fully extracted product folder.
If you prefer to go the direct-download way, open only the first part (.part1) of the archive collections, the other parts will be extracted automatically. Make sure you don't start the extraction process before your download of all the parts has completely finished.
We've used Entropy to archive our bundles. (Mac)

When downloading your product(s), many of them have a combined file structure. This means that the files, although individual in nature, are of one archive. So in order to extract the contents of these files you will need all of the files in the "Combined Files" group.
What happens when you extract a zip or rar archive either from a single archive file or Combined File Structure?
Well, The files will be extracted to your computer from the single or combined archive, into folders and files in those folders. For rar files only the first volume (Part1) has to be opened! The other parts will be extracted automatically.
We have to split up our volumes to make them better downloadable and provide fast download speeds for everybody.
