strange .htaccess on my host
===

Today I enter my website and it's freak out. All css can't be loaded, all images too. I didn't update anything in my website for a few months. I investigate through the theme folder and found a .htaccess file in there (I used wordpress), and it' content.

Could any one can explain the meaning of this .htaccess file. ATM I don't have any ideas why this file appear in my host.
