One way is to use the "download" function in the control panel, but for hundreds or thousands of files, that gets real old real fast. Have you looked at installing an "FTP Client" on your PC? FileZilla is the 800 pound gorilla. Once you have FTP configured, you can download all your files in one operation -- fire it off and forget it.
P.S. it's not a good idea to give your email address as a public ID. The whole world will be spamming you now.
