Editing files with FileZilla

Hey there ppls... I've just downloaded filezilla to use on my usb drive. I am hoping to be able to edit files from the server directly - I've figured out how to edit the file (e.g. I've set up the connections in the settings area, and I can right click on the file and choose 'view/edit', where I can then edit the file using my chosen editor), however when i save the edited file, it doesn't upload the new one - I have to manually find the file and upload it. Is there something I'm missing to make this easier?

Thanks,
