I deleted a file and emptied the Recycle Bin, but I cannot find the file to undelete. Where is it?

When a file is moved to the Recycle Bin, Windows changes the filename. It has the same filename extension, but a different filename. You need to search for the file based on the extension, date and time, etc. There is no way to retrieve the original filename (the filename used before that Recycle Bin was emptied).
