Dear [@Wayne K]
Thank you for your question. This program is a WPF (Windows Presentation Foundation) application written in C#.NET language. That makes it bit more memory consuming than for example native C++ application. I just opened Task Manager and it shows 52MB. It is bit more than I would wish but already completely empty WPF application attacks 50MB border as you can read here. If you meant disk space then its usage is negligible. I dare to say that as a user you would not notice that Clipà.Vu is running in the background.
