如何从applicationStorageDirectory中删除文件？

Question

我想删除cordova.file.applicationStorageDirectory中的所有文件，问题是我没有文件名，而且我找到的每个代码都需要文件名。

这是一个例子。

var path = "file:///storage/emulated/0";
var filename = "myfile.txt";

window.resolveLocalFileSystemURL(path, function(dir) {
    dir.getFile(filename, {create:false}, function(fileEntry) {
              fileEntry.remove(function(){
                  // The file has been removed succesfully
              },function(error){
                  // Error deleting the file
              },function(){
                 // The file doesn't exist
              });
    });
});
