Dropbox Transfer lets users send up to 100GB of files
More importantly, you don't even have to own a Dropbox account to be able to receive files through Transfer. According to Dropbox, the entire process of sending such a large quantity of files is quite simple and fully automated.
Simply drag and drop files to upload from your computer, or add some that are already in Dropbox. Once the transfer is created, you'll get a link that can be pasted anywhere. The link can be sent to anyone, or you can simply send an automatically generated email directly from Transfer. Recipients will receive copies of the files, which means originals will remain untouched.
Dropbox Transfer comes with a set of tools that will allow users to fully customize their experience. For example, it's possible to add, edit, or remove a password, as well as set and change an expiration date, even after you send a link. Last but not least, you have the option to receive download notifications to find out when your files have been received and how many times the link has been accessed.
For the time being, Dropbox Transfer is available in beta to select users and will be launched to all Dropbox users soon, so if your account is in the beta program, you should receive an email with more info on how to start using the new service.
