Where is the download?

Graham asked 10 months ago

Hi 
I just downloaded you Go To Top Widget (I think?), but I cannot see where it was downloaded to.
I filled in the form and clicked the Download button and the animation ran. 
But where is it? I cannot see it in my download folder. 
I have searched my computer for every file modified in the last 20 minutes. What is the filename?
Is there something else I need to do before it is downladed?
