You can configure the Dropbox Destination in ZipTite to make it simple and quick to share files via your Dropbox.

To start, when you drop files onto the Dropbox Destination, ZipTite creates a Zip Archive and places it in your Dropbox for you.

After that, you can configure the Dropbox Destination, to take one or two more additional actions:
Create Share Link

First, you can have ZipTite create a Dropbox Share Link to the newly created Archive and place it on your Mac's Clipboard.

Send Share Link

Second, you can have ZipTite send the newly created Dropbox Share Link via Email or Messages.

All of this makes it very simple to share files via Dropbox: just drag the files and drop them onto the Dropbox Destination and let ZipTite do the rest.
