To save it, use file I/O functions, perhaps look at examples if you get stuck.
To retrieve from the computer, I'd use an ftp client. If you don't have a good one, you can type
ftp:///10.xx.yy.06 into the address bar of an explorer window. Navigate to the location you saved the files and drag the file back to the PC file system. Just beware of caching with the Windows Explorer based ftp. It usually works, but sometimes shows you stuff that isn't really there.
