Textastic

This must be a really stupid question. Do you know if I can create new files with Textastic? I have looked through a lot of similar apps, like Koder, etc., but they only mentions that they can use FTP to upload/download files, but they didn't mention whether they can create files within the app.

Since my iPad doesn't have 3G connection, it will be nice if I can create simple HTML/CSS files on the go. Thanks a lot!
