Question

I want to traverse through each file in the SD card inside all the directories and sub directories using the FILE API of phonegap (which is the w3c file api actually). I have to perform a certain set of operations on these files by looking at their nature. I donot want to search for specific types of files, but traverse through each file in a sequential manner.

Can someone please help me with this? Just a basic loop framework with the necessary requirements for the traversal would be a great help.

Thank You in advance.

I think the following code should work:

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onRequestFileSystem, fail);

function onRequestFileSystem(fileSystem) {
    var directoryReader = fileSystem.root.createReader();
    directoryReader.readEntries(onReadEntries, fail);
}

function onReadEntries(entries) {
    var i;
    for (i = 0; i < entries.length; i++) {
       if (entries[i].isFile == true) {
         // ...
       }
       if (entries[i].isDirectory == true) {
         var directoryReader = entries[i].fullPath.createReader();
         directoryReader.readEntries(onReadEntries, fail);
       }
    }
}
