PhpStorm - why css files are not uploaded?

Question

css

I work with an FTP project, I write css using less, so after editing, only the less file is uploaded to the server.
I use Ubuntu 13.10, while my colleague on Mac OS is fine (less is configured in exactly the same way).

The problem was solved by checking the box in the settings:
Settings => Deployment => Options => Upload external changes
