Lost downloaded file.

I downloaded a 50mb zip file (Radiohead Album) from the web browser this evening and I can't find it! My available memory has decreased by the same amount - coincidence?

Is there any way I can find it, move it delete it?
Is there any way to see other files that may be hidden?

Thanks in advance.
