I have a folder structure like in the following picture. The less node.js I would compile with. I am calling the compiled CSS file in the meta-tag section.
When a change is made in the less file, the CSS file is automatically loaded on to the server I want to be.
Summary : If style.less changes in style.css to upload to the server. Thanks for your help.
I solved the problem. Tools->Deployment->Options -> Upload external changes chose.
