File[] Files = root.listFiles();
if(Files != null) {
    int j;
    for(j = 0; j < F         


        

Answer 1

// Delete folder and its contents

public static void DeleteFolder(File folder)
{
    try
    {
        FileUtils.deleteDirectory(folder);
    } catch (Exception ex)
    {
        Log.e(" Failed delete folder: ", ex.getMessage());
    }
}

// Delete folder contents only

public static void DeleteFolderContents(File folder)
{
    try
    {
        FileUtils.cleanDirectory(folder);
    } catch (Exception ex)
    {
        Log.e(" Failed delete folder contents: ", ex.getMessage());
    }
}
