Recently I wanted to recreate my DotNetNuke websites on a new installation.  So, I brought up a new DotNetNuke website and database.  I then created portals on my new server to match that on my old server.  I then copied the files from each portal directory from the old server to the new server.  Lastly, I copied the skins and containers from _default to the new server.  Everything went well and I set about recreating the sites.  

When I got to working on recreating the users in the portal, I noticed that all of the user accounts and profiles from the old site were already listed in the new site.   I started doing some digging and all of the profile information for all of the users were there too.  I went to the database and looked a the Users table.  All of the accounts (~20) were created within a few seconds of each other.  I then looked at the UserProfile table and the LastUpdateDate date time stamp is at the same time as when all of the accounts were created.  When I look at the aspnet_Membership table, All of the CreateDate, LastLoginDate, and LastPasswordChangeDate date time stamps are about 6 hours later than the dates in the other tables and they all happened within a few seconds of each other.

I said all of that to say, how could this have happened?  Is all of the user account and profile data stored some place in the portal folders?
