There is an activity called “Get from Clipboard”, which can pretty easily save a filepath on the clipboard into a string variable.
I’m not sure of what you’re trying to do after that.
If you’re just trying to open the folder in windows explorer (what happens when you double click a folder on your desktop), you should be able to do that using an “Invoke Power Shell” activity. It would go something like
explorer C:/RPA
Note that C:/RPA is just a folder I keep on my work computer, and this would only work if the path on your clipboard is an absolute path.
