Downloading my site from the internet


I recently lost my entire hard drive and my web site was not something I had backed up on a disc or on my external hard drive. Lord only knows why.

I was trying to SmartFTP to download my site straight from the internet so I could make any necessary changes. But when I have tried to drag and drop, and copy and paste I get the following message:

"The system cannot find the file specified."

There's always 3 or 4 of these messages also. Any thoughts on what I need to do or why I'm having this problem?

Thanks in advance for the help.
