Which file we should upload to server .scss or .css when we use Sass?
I read about Sass and Compass it makes these folders and files

I write scss in which gives output in .css file of same name.
My question do i need update whole folder to FTP or just .css file.?
I work with both .net and .php based websites.
the css is what the html pages will refer to. So thats the one you need to upload.
For source control, you only really need to keep the sass.
