If you view/edit a file in Filezilla after connecting to your server, it won’t automatically open using your default text/code editor: Rather then open your files using text/edit, notepad or your browser, a better and safer option is to open your files using your code editor. If you don’t configure these settings In Filezilla, your files may open using notepad in Windows or text/edit in Mac which isn’t safe to edit. Windows users might want to set Notepad++ instead. In this case, all files will open using Text Wrangler for Mac users. This post shows you how to change your Filezilla settings so any file you view/edit in Filezilla, opens with a specific application.
