So the app I intend to develop will connect to the proxy network and let this app (directly) access the internet through it.

This app basically puts the last ten or five files that has been copied in a temporary location
The clipboard can be used for many other things, not just files. Also, a file, who you described, doesn't get put on the clipboard. The path of a file might be there, but not the file itself. You're going to have to go into much greater detail defining what this app is going to do before you even start this.
I NEVER copy a file to the clipboard and then paste it somewhere else. I always drag and drop it/them. This operation never involves the clipboard.
