Dropbox just released a new extension for Chrome—called Dropbox for Gmail—that lets you add links to your files and folders at the click of a button in your email. The release is currently in beta and free to download. This is particularly handy if you’re a power-user of Dropbox’s Selective Sync feature as it opens up your master Dropbox files in the cloud, and not just the folders you have access to on your computer.
Once you click on the Dropbox icon, you’ll see the familiar Dropbox uploader pop-up within your Gmail window.
I’ve been a fan of Airmail for my Mac, which also has a Dropbox integration, but it works differently than the Gmail extension. Instead of attaching a file, you select the file you want to send. Airmail uploads that file to your Dropbox account and sends the link. This seems like a helpful shortcut for sending large files, but in reality, I usually have those files already stored in my Dropbox account.
I suspect we’ll see a similar feature to the Gmail for Dropbox in Dropbox’s own Mailbox soon, although it’s not currently available.
