Since the Yahoo! groups have switched to new version 'Neo', the list of folders and files in the Files section are displayed in a totally random order (instead of folders first, then files directly uploaded into the Files sections). What's more, I can't access any folder (message 'oops! Invalid path') and I can't upload files in the folders I've created but only directly into the Files, which makes a big disorder. I tried it with my 3 browsers, IE, Chrome and Firefox with same results. Upgrading the Files section to 2GB is great, but it's of no use if it doesn't work correctly.
