Answer 1

Served my source code to the PhoneGap developer app. My file copy code is below.

   //COPY FILE
   var wwwDirEntry;

   //resolve url for directory entry for putting in copied file
   window.resolveLocalFileSystemURL(cordova.file.dataDirectory+'phonegapdevapp/www/', function success(dirEntry) {
       wwwDirEntry = dirEntry;
   });

   //resolve file URL to file entry to enable copying
   //
   //Desired URL: file:///data/user/0/com.adobe.phonegap.app/files/phonegapdevapp/www/my_awesome_file.doc
   //BASE URL: cordova.file.dataDirectory / file:///data/user/0/com.adobe.phonegap.app/files/
   //
   //alert(JSON.stringify(cordova.file.dataDirectory));
   //
   window.resolveLocalFileSystemURL(cordova.file.dataDirectory+'phonegapdevapp/www/my_awesome_file.doc',
      function onSuccess(fileEntry)
      {
          //alert(JSON.stringify(fileEntry));
          fileEntry.copyTo(wwwDirEntry, 'a_copy_of_my_awesome_file.doc',
          function()
          {
              alert('copying was successful');
          },
          function()
          {
              alert('copying FAILED');
          });
     }, function (e) { alert(JSON.stringify(e)); });
