DropBox allows files upload with only the following file extensions (see list below). If your extension is .db, .db3, or Sqlite3, it will not allow you the upload. In that case, you need to contact their tech support via their site and request that they add , for example .db to your application. They will do it. I had them do the same thing for me. I have requested that they add the extension universally since .db is a very popular extension, but they only did it to my specific application.
