Totally agree. With 50 attachments I would be needing such a feature. Luckily I don't have that many files but you never can see what the future brings so it's get's a like for this suggestion.Absolutely, primary option - single files. But somehow when needed - the lot. I use my site as a document library and sometimes one post can include up to 50 files.
Maybe a shopping cart styled functionality, where you can add things that needs to be downloaded and add them into one giant zip file?Sure, but is that what's being asked for here? The request like a desire to have the browser individually download multiple files automatically.
