The following code can be used to extract files that are greater than 1MB under any specific directory (using LINQ).

private static void GetFiles(string Path)
   {
try
{
    DirectoryInfo directory = new DirectoryInfo(Path);
    FileInfo[] files = directory.GetFiles("*.*", SearchOption.AllDirectories);
 
    var query = from file in files
                         where file.Length > 1024*1024
                         select "File Name:"+ file.Name + " File Size: " + file.Length.ToString();
    foreach (string str in query)
    {
           Console.WriteLine(str);
    }
}
 
catch (Exception ex)
{
       Console.WriteLine(ex.Message);
}
     }

 
– Call the above defined function in Main() like

GetFiles(@”E:\books”);

It will return all files that are greater than 1 MB.
