Hi Katherine101,
Might I suggest an FTP application/program that will allow you to accomplish this "upload": FileZilla.
Should you be curious please visit my
tutorial, "
Basic Navigational HTML/CSS Website From Template: Download To Upload, A Step-by-Step Tutorial For The Novice", and please make reference in reading from "Step 17" and, mindfully, be aware and attentioned to the "
Red Letter" information at the beginning of the tutorial as it contains some pertinant information
(actually... the entire presentment is, and makes for some, useful information) to the
FTP Upload Process here at Zymic.
There are other FTP applications/programs available so if you choose not to accept my response here, for whatever reason(s), that's quite alright...
everyone marches to their own drum.
Hope this helps you out, Katherine101.
