I’ve been using TeraBox for my edit, it’s full of ads and isn’t too user friendly but it’s a free terabyte of cloud storage.
That being said, I do get a lot of DMs about people who want the edit being confused. And I try provide a more known alternative for those sceptical of or unable to use TeraBox.
The limits on mega can be avoided if you use an internet downloader rather then Megas download software itself or in built browser downloaders.
