There will be a Install Utility that will install any Zip file to your Content folder as long as the file structure is set up correct. When it (the Utility) is Released to the Community you can look for all Downloads to go to Zip very fast.
... and a breakdown of the DAZ servers. That’s why I still say they should release new content in zips also so there won’t be such a stampede to download everything. In fact they should start releasing older items weekly and informing the community as released.
