Removing files from site

I just established my connection and all of the files from my website show up.

How do I remove those files and enter files that I would like to have in there.

Help please.

Thanks,
BC

select the file you want to remove and press "del" on the keyboard or select "delete" from the context menu (right mouse button on a selected file), just as you would do in windows explorer to delete local files.
to upload, select the files you want to upload in windows explorer, drag them over to the smartftp view of remote files and drop them there.
