Windows 7: deleting files

Hello, first time for me..apologies not very techy, is it okay to delete the hundreds of foreign language folders I have on my laptop. They came installed and seem to be every possible language. I have deleted some, now panicking!

You can delete them. But what does it really buy you. An itty bitty amount of disk space - not worth the trouble.

Ok thank you, just thought they were unnecessary clutter. I will leave them alone.

Yeah, if you want so, they are clutter. But they are quietly sitting there and do nothing.

Ok, no problem, get what you are saying. Kind Regards.
