Is there a file selector in corona sdk?

Thanks for the answers.I think that i found the plugin.

I cannot log in to the Google Marketplace. It demands to reconfirm my postal address. It looks like I have stated the wrong zip code when sighing up. Now I check over here the correct zip code. But how to amend it in my details. Do you think it will be better to create a new account and forget about the old one? Or is there any chance to contact a support team? Any help will be much appreciated.
