Im somone who cant make income yet, so buying online cloud is out of the picture. Im pretty sure there isnt any other large scale free space so its been basicly my only option for months😭
I've been using Terabox for 6 months now and it's still working. I uploaded many ISO files and lots of movies/tv series.
I don't suggest you to upload sensitive files and to accept the risk that they can suddenly remove all your data without advising you. They haven't done yet, but they could do that (also Google did that with unlimited storage).
If you want to upload videos or other stuff that isn't very important for you (like videos that you can re-download anytime) probably it is fine, but if you want to store important data I don't recommend it.
