Friendly SEO URLs

Question

I need to know how to make SEO friendly URLs, say I have a URL in this format http://www.domain.com/file.php?v1=a ... Now I need users to use http://www.domain.com/a and this redirects to the previous ...

How can this be achieved?

And for say http://www.domain.com/folder1 how can I force it to go to http://www.domain.com/folder2 via .httaccess?

Thanks in advance.
