Copying a file using Cordova

Question

I\'ve been trying to copy file named versions.txt from applicationDirectory to externalApplicationStorageDirectory using cordova but code fails.

here is the code

Answer 1

The fileEntry.copyTo somehow always gave error, so I tried the fileEntry.moveTo as below, which works well for me in copying any file from the www into say the Library folder of the iOS device.

function copyToLocation(fileName){       
console.log("Copying :"+fileName);
    window.resolveLocalFileSystemURL(cordova.file.applicationDirectory+"www/"+fileName,function (fileEntry)
    {
        window.resolveLocalFileSystemURL(cordova.file.dataDirectory,function (directory)
        {                  
           fileEntry.moveTo(directory, 'new_fileName.txt',function(){
                alert('Successful Copy!');
            },
            function()
            {
                alert('Copying Unsuccessful ');
            });
        },null);
    }, null);
 }
