Google gives you 15gb of space, but you have to share it between your emails, documents, etc.
You reminded me that in addition to OneDrive and Dropbox, I use Google drive for my really non critical files and 15Gb is more than enough for me. I confess I haven't explored what's possible but on first acquaintance I really don't like the way Google drive is structured or the way it works. I want a simple file list that looks like windows File explorer and nothing more. Trying to be different is not helpful, they even make hard work out of deleting files. When I delete a file nothing seems to have happened until I refresh the page. Who thought that was good idea.
