Hello, Is it possible fill NSpastebard with public.file-url which will initially point the an empty file. And when Finder will paste the file, my Application will download it and Finder will wait for the completion of the download.

My goal is not to use drag & drop.

I saw that Microsoft RDP client is doing file download using this way. But I don't know how it works. Empty file is created in sandbox.

NSFilePresenter seem to be what I need. An exemple is done here https://github.com/lemonmojo/RemoteFilesVsPasteboard

The word you’re looking for here is promise. You vend a file promise and the receiver calls in that promise after the drop. I don’t know how to do that with AppKit [1] but knowing the right search term should help you find the info you need.

[1] I could tell you how to do it with the traditional Mac OS Drag Manager, but I don’t think that’ll help you very much (-:
