What is Up1?
Up1.ca is the simplest file hosting application you'll find on the internet. You just have to drag-in the file you want to share and the application will handle it. You can share any file you want with your friends in a more secured way as the file is encrypted on the client side. It also integrates a "Paste" editor, a PDF viewer, and mp3/video player.
The project seems to be no longer developed since August 2017. Last version, 1.0, released in February 2016, can be still downloaded from GitHub.
