# Bug Report

## Problem

### What is expected to happen?
I should be able to read a FileEntry's metadata no matter how I got hold of the object

### What does actually happen?
I retrieving the FileEntry handle directly via `resolveLocalFilesystemURL` I can call getMetadata() on the returned object without an issue; but if I obtain the handle by reading the parent (root) directory, the call will result in NOT_FOUND_ERR`

### Command or Code

I am running the below code in the `deviceready` event handler:
```
console.log('Running cordova-' + cordova.platformId + '@' + cordova.version);

function errorHandler(e) {
console.error("Error: ", e);
}

function testFileMetadataRead() {
console.log("Successful file write...");

window.resolveLocalFileSystemURL(cordova.file.dataDirectory + "/test.txt", function(file) {
console.log("Contructor of FILE handle", file.constructor);
file.getMetadata(
function (m) { console.log("Getting FILE metadata", file, m) },
function (e) { console.log("Error getting FILE metadata", e) }
);
}, errorHandler);

window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dir) {
dir.createReader().readEntries(function (entries) {
entries.forEach(function(entry) {
console.log("Contructor of DIRECTORY ENTRY handle", entry.constructor);
entry.getMetadata(
function (m) { console.log("Getting DIR ENTRY metadata", file, m) },
function (e) { console.log("Error getting DIR ENTRY metadata", e) }
);
});
}, function (e) { console.log("Error listing directory", e) });
}, errorHandler);
}

window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dir) {
dir.getFile("test.txt", { create: true, exclusive: false }, function (fileEntry) {
fileEntry.createWriter(function (fileWriter) {
fileWriter.onwriteend = testFileMetadataRead;
fileWriter.onerror = function (e) { console.log("Error writing FILE", e) };

const blob = new Blob(["The quick brown fox jumps over the lazy dog!"], { type: 'text/plain' });
fileWriter.write(blob);
});
},
function (e) { console.log("Error creating new file", e) });
}, errorHandler);
```

Commencez par la reproduction de deviceready en utilisant resolveLocalFileSystemURL, createReader().readEntries() et getMetadata(), en comparant le FileEntry résolu directement avec l’entrée renvoyée par le répertoire. Reproduisez le problème avec les versions indiquées de Cordova Browser et file-plugin ; c’est terminé lorsque la récupération des métadonnées réussit pour les deux handles sans NOT_FOUND_ERR.
