You need to use the File plugin. Some basic example code here:

window.resolveLocalFileSystemURL(DIR_FULL_PATH, function(dirEntry) {
    var directoryReader = dirEntry.createReader();
    console.log(dirEntry);

    // Get a list of all the entries in the directory
    directoryReader.readEntries(success,fail);
});

function success(entries) {
    var i;
    for (i=0; i<entries.length; i++) {
    //Here you can check the entries ofject for the file name and do stuff    
    console.log('En - ', entries[i]);
    }
}
function fail(error) {
    console.log("Failed to list directory contents: ", error);
}
