Most likely, your recipient opted to "Open" the file when it was downloaded instead of saving it to a specific folder. In this case, the file is still on your recipient's computer, but it's most likely stored in their "Temporary Internet Files" folder.
What I would suggest that you tell your recipient, is that when they get prompted to either "Open" or "Save" the file in question, that they save the file into a directory that they can easily access on their computer. For example, their Desktop.
