multi-language website - question about robots.txt & SEO

Right i have a website that is in 7 languages.

i have submitted each language to webmaster tools as a separate site targeted geographically for the country except the root which is English & worldwide.

each site is hxxp://-------------/en/ hxxp://-------------/bg/ etc

i was trying to block Google from viewing the directories for all the languages except the English site so that i can track each language results separately.

i figured a separate robots.txt in each directory would work but the robots from the root domain took over for all.


Any suggestions how to do this or another alternative?

I think i should i have set them up as sub domains but this would require a lot of effort to change as i designed the site fully myself & there is 120+ pages - no wordpress

I cant really help you out a lot, I have multi-lenguage sites as well but I use wordpress
and Qtranslate and only 1 robots.txt
