I'm sorry, I should have been more clear in the midst of the Yahoo fiasco: I meant the exported group data from Groups.io, not Yahoo. I've changed the subject to clarify too.
G.io has an option to download various group data, which is useful especially for larger groups that can't stay in the paid 10GB or free 1GB storage limit. I tried it out for one of my groups, and requested the member list, messages, group description, and cover photo. I got files back in multiple formats, a couple JSON, an MBOX, and the photo just says FILE. So once downloaded, how do I access those files? Is there one program that can open them all, or does this require multiple programs?
Thanks so much.
