l'instruction API, et ne pense pas qu'il y ait quelque chose de mal avec ce code "copyTo".
En outre, il y a le dossier "Documents/dest" et le fichier "Documents/readme.txt"
http://docs.phonegap.com/en/1.8.0/cordova_file_file.md.html#File

**var FileSystem = { 
    copy : function(src, dest){ 
    var parentEntry = new DirectoryEntry({fullPath:("/dest")}); 
    console.log("parent_entry := " + FileSystem.root_path+"/dest"); 
    function gotFS(fileSystem) { 
     fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail); 
    } 

    function gotFileEntry(fileEntry) { 
     fileEntry.copyTo(parentEntry, "file.copy", function(e){console.log("copy okay");}, fail); 
    } 
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); 
    } 

}**

copy : function(fromUrl, toPath, toName){ 
     console.log("copyFile - From: [" + fromUrl + "] To: " + toPath + " Name: " + toName); 
     // Set up some storage 
     var destPath = ''; 
     var destName = ''; 
     doMoveFile(fromUrl); 
     // Called when file needs to be moved/after capture 
     function doMoveFile(fileUrl){ 
      //console.log("doMoveFile - fileUrl: " + JSON.stringify(fileUrl)); 
      // Remember the source file name just in case it was not passed so reuse it, and for logging 
      var destName = fileUrl.name; 
      var destPath = fileUrl; 
      // Resolve the file system 
      window.resolveLocalFileSystemURI(fileUrl,resFSSuccess, resFSError); 
      // Called upon successful File System resolution 
      function resFSSuccess(entry){ 
       //console.log("resFSSuccess Success - entry: " + JSON.stringify(entry)); 
       // Request a file system 
       window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, 
             requestFileSystemSuccess, requestFileSystemError); 
       // Called upon successful File System request 
       function requestFileSystemSuccess(fileSys){ 
        // Get the source directory 
        fileSys.root.getDirectory(toPath, {create: true, exclusive:false}, getDestDirSuccess, getDestDirError); 
        // Called upon successful Get Of Destination Directory 
        function getDestDirSuccess(directory){ 
         // Get the destination file name, set it if it is blank or not passed by the App 
         toName = (toName) ? toName : destName; 
         // Remember the full path name for the console log 
         fullDestPath = directory.fullPath + '/' + toName; 
         // Make the move 
         entry.copyTo(directory, toName, moveSuccess, moveError); 
         function moveSuccess(){ 
          console.log("Successful copy of " + destPath + " to " + fullDestPath); 
         }; 
         function moveError(error){ 
          console.log("copyError code: " + JSON.stringify(error)); 
         }; 
        } 
        // Get Destination Dir Failure 
        function getDestDirError(error){ 
         console.log("getDestDirError code: " + JSON.stringify(error)); 
        };  
       } 
       // File System Request Failure 
       function requestFileSystemError(error){ 
        console.log("requestFileSystemError code: " + JSON.stringify(error)); 
       }; 
      } 
      // Note File System failure 
      function resFSError(error){ 
       console.log("resFSError code: " + JSON.stringify(error)); 
      }; 
     } 
    }
