ASP.NET Application and ASPNETDB.MDF
<p>I've built an ASP.NET application and noticed that my /App_Data folder contains two files: ASPNETDB.MDF and aspnet_log.mdf.  They total about 10MB in size.</p>

<p>I'm handling security via an Oracle database and authentication mode = "Forms".</p>

<p>Why did these files get created?  Is it safe to delete them?</p>
