I use we transfer a lot to send big files to people all over the world!

With we transfer we quickly share files with our external providers, in this way we avoid saving things in our cloud of things that we will not need in the future, an important thing that the links are active for a maximum of 2 weeks

Seamless transfers, easy uploads, secure links, I believe they also encrypt the data so that everything is extra secure. I've used this to request for files and I've had no problems whatsoever
