Moving wordpress, and its files….

Hi, I am wondering if there is any way to move the physical files of wordpress, to my main domain. For example, all the files are at vardox.com/blog, but I wish to move them to the index (vardox.com) I have gone to the settings, and made it so it appeared that my blog is a vardox.com, but this has given me SEO issues. So would there be anyway to back up my entire blog and move the physical files?

Thanks,
Vardox
