One of the things I like about zotero is I can keep my articles organized in groups. when I do a search let say by a keyword in the title, I often want to know what group I stored the article in. Any idea how I can get this kind of functionality

You can think of it as follows. I use search to find a file on my computer. I want to know what directory or folder the file is in

It would be really handy if zotero was more like a file system. files get downloaded and stored in a flat space
