I am interested in writing a Premiere plug-in that can upload/download files to a URL from Adobe Premiere. Is there API functionality that lets me do this? More generally, is it possible to write this into a plug-in?
Moved to the programming sub-forum
PPro panels are (basically) web pages, and can upload/download files, using common web frameworks, as you wish.

What are you trying to build? Feel free to write me directly; bee bee bee at adobe dot com
