To move files across the Web you will need to make use of  some FTP software (File Transfer Protocol).This is essential when you consider you may want to upload content from your local machine to your web site.

There are many hundreds of software packages that can acheive this but again I was not looking to spend any money.

Fortunately SimplyBeHosted supply Filezilla for FREE so I am using this.I was a bit daunted by this at first but once set up its a case of browsing to the folder on your web server and dragging the file you want to upload ,easy.
