Dropbox released new add-on for Gmail
Dropbox announced a new add-on to manage Gmail attachments in Dropbox. It displays the attachments in a side panel after which you can save them if you so choose directly into your Dropbox, and the experience is the same in the mobile app or on the web. Being able to access Dropbox without leaving Gmail or other G Suite tool could potentially save users time and effort spent copying and pasting and switching programs. It's a somewhat surprising partnership, as Google and Dropbox compete on the cloud storage front: Google Drive storage has many of the same features as Dropbox.
DropBox alternatives are: Box, SugarSync, OneDrive, Evernote, Google Docs, iCloud, Salesforce
