There are 6 panes inside FileZilla, which can appear confusing so hopefully I'll explain it the easy way.

Very top: This is where you'll see your connection once you've hit the 'Quickconnect button'. Unless there are any issues with your login this should be a simple proccess. If you recieve any error code I suggest you contact WA support.

Top Left: Here you will see all your documents on your PC.

Top right: Here you will see all your folders for your website. The only folder you need to open is httpdocs, which is the 3rd one down.

Bottom Left: Here you will see what folders you want to upload to your website, but there will be nothing into until you start opening up folders in the top left pane.

Bottom Right: Here you will see all your files from your website when you click on the folders in the top right pane.

Very bottom: This is where you will view the uploading or deleting of files and folders.

TIP: You can move each pane up and down to make them bigger or smaller to get a better view.
