Linq - Find the size of a Directory

In this article we are going to see the usage of EnumerateFiles and EnumerateDirectories in Linq and how it is working.

EnumerateFiles() : Will enumerate the files present in the folder 

EnumerateDirectories() : Will enumerate the Directory present in the folder.

/* Directory Size*/

   long _size = Size(@"D:\flot", true);

   Console.WriteLine("Directory Size in MB : {0:N2} MB", ((double)_size) / (1024 * 1024));

          

   static long Size(string path, bool includesubdir)

   {

            DirectoryInfo info = new DirectoryInfo(path);

            long _size = info.EnumerateFiles().Sum(x => x.Length);

            if(includesubdir)

            _size+=info.EnumerateDirectories().Sum(x => Size(x.FullName,includesubdir));

           

            return _size;

    }

Output :

Directory Size in MB : 2.14 MB
