Thanks, but I already am zipping the “grouped content” which I mentioned. It works great: the downloaded zipped file is sent to a file manager (I use “Documents”) and unzips exactly as I want.
But my question is how do the same with multiple zip files; that is, “groups of zips”. Hope that makes sense. Also, I’m trying to avoid the brute force approach of uploading separate “groups of zips” – an unnecessary waste of space.
