The benefit of such a file-sharing platform is that you will not only be able to send the files but also you will be able to track whether they have been delivered. The Facebook developers, in early 2016 foresaw these challenges and developed features within the Facebook messenger to enable you to seamlessly share all Dropbox files on the Facebook Messenger as normal messages. If you use Facebook Messenger to chat with friends and co-workers, you need not experience such setbacks when sending files. You will agree with me that this is cumbersome and inconvenient. This implies that you will have to move from the messaging platform, open your email app, send the message, and then go back to the messaging app to alert the person on the other end that you have already sent the file.
The next option was likely a request for their email address so that you can send such a file. Have you ever chatted with a person over a messaging app and then it reached a time you wanted to share a file with them.
