DO NOT ADD ANY FILES!
All the required files exists in your site!

You must only CHANGE some style rules in the corresponding source CSS files!
(And the clean Template cache and clean template style cache)

I.e. In English you see (using element inspector) the file used: style_1_forum_guide.css
In Arabic will be used corresponding RTL file: style_1_forum_guide_rtl.css

After modifying some style rules online
you must ADD/CHANGE that rules INTO THE SOURCE STYLE FILE!
In above cases it will be the files:
data/cache/style_1_common.css ->  EDIT THE /template/default/common_rtl.css
data/cache/style_1_forum_guide_rtl.css ->  EDIT THE /template/default/forum/guide_rtl.css
