Select a file on your web site from the navigation treeview on the left of the Zoom Website Editor main window.
Non-text files such as images are downloaded over FTP from the web site to your My Documents\WebSites{domain name} folder or subfolder. The "edit" command is passed to Windows which will open the file in the Windows default external application for edit.
Once editing is complete in the external program then the Zoom Web Editor menu item "Upload this File to Web" may be used to return the edited file to the web server.
Text files (generaly HTML, CSS or code script) are downloaded from your web site into a new Zoom Website Editor tab. Each editor tab contains a text editor, a web browser (it is a limited version of IE and therefore a rubbish browser but it gives some idea of what the page will look like) and a history tab. Multiple editor tabs allow a number of files to be open for editing all at the same time. If you mess-up then you can "undo" current edits or retrieve an earlier version of your web page from history.
Once editing is complete, any pre-existing disc file is saved to history, the new file is saved to your Documents\WebSites{domain name} folder (or a subfolder of it) and then uploaded to the web site via FTP.
