No, the Documents folder is your app's private area into iPhone, and It is used by the app to store files. (ie. saveToDocuments function)
That is the space where the sqlite files are copied during the first access so it can be used inside your app.
everything you save is stored there.. so you can access it by name. You can't build subfolder into Documents..
My english is not so good, I hope everything is clear for you, you can find many other posts in the forum..
