You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.
Most businesses need to send files via sFTP for various reasons. I am not sure why Dropbox does not provide SSH as an option to upload and/or download files.
I will add... most companies want to automate file transfers as much as possible. sFTP is what makes this capability possible, especially from midrange systems like IBM i, IBM Power AIX and Mainframe systems...
If sFTP support was added, a company could trigger a script from an internal process to land in a desired DropBox folder. Or, if expecting files, the application could monitor the folder for any new files meeting 'xyz' criteria.
