Facebook Messenger is a great way to stay connected with friends and family, but it can be difficult to share files with others. If you want to share a Dropbox file with someone on Facebook Messenger, here’s how to do it. First, open Facebook Messenger and find the person you want to share the file with. Next, click on their name in the top left corner of the screen. Then, click on the three lines in the top right corner of the screen. This will open up a menu where you can select “Files.” Next, click on the “Dropbox” icon and select the file you want to share. You can then choose how you want to send it: by emailing or sharing via Facebook’s social media buttons. ..
