Dropbox has two features: DocSend and Transfer.
Both are used to send files.
I am looking for an article that describes the difference between these two features.
Hi there @net90s, thanks for using Dropbox and welcome to the Community!
There's no Help Center article outlining the difference between these two, but you can have a look at this page and this Help Center article for more information about both of them.
In essence, you can use Dropbox Transfer to deliver large files while DocSend is used for sending content you want to get in-depth receiver engagement insights on (eg. how much time a person spends on each page of a PDF).
I hope this helps a tad and please let us know if you have any follow up questions.
