we published an article on how to upload files to server on our site. it’s pretty easy to use ftp software actually, just read the article.
however, the free ftp software i mentioned in the article is not available any more. the vendor company has stopped providing the free lite version. they still offer paid version. 30 days trial download is free. but to be honest, paid version is not as easy to use as the free light version. you won’t do all those fancy stuff via ftp software, will you?
luckily, there’re still free ftp software. go to download.com and search for ftp.
