I want to be able to share folders of files across different devices so that they sync when connected to a network but have the files available when offline and of, course, I'd rather not have to pay.
It seems that google drive will only do what I want on a file-by-file basis; the free version of Dropbox won't make files available offline. I've thought about evernote but can't find a definition of what it considers a note ... will it do what I want (file types are mostly pdf, txt and abc). Is there anything else I should look at?
[Some of the files relate to DIY, so there's a (tenuous) link.]
