We've gotten a few questions about whether you can put multiple Sitemaps in the same directory. Yes, you can!
You might want to have multiple Sitemap files in a single directory for a number of reasons. For instance, if you have an auction site, you might want to have a daily Sitemap with new auction offers and a weekly Sitemap with less time-sensitive URLs. Or you could generate a new Sitemap every day with new offers, so that the list of Sitemaps grows over time. Either of these solutions works just fine.
