Here’s a version of the directory size calculator that also:

class Program
{
    static void Main()
    {
        string folderPath = @"C:\MyFolder";
        if (!Directory.Exists(folderPath))
        {
            Console.WriteLine("Folder not found.");
            return;
        }
        long totalSize = 0;
        var extensionCounts = new Dictionaryandlt;string, intandgt;(StringComparer.OrdinalIgnoreCase);
        Console.WriteLine("Processing files...");
        var files = Directory.EnumerateFiles(folderPath, "*", SearchOption.AllDirectories);
        int fileIndex = 0;
        foreach (var file in files)
        {
            try
            {
                var fi = new FileInfo(file);
                totalSize += fi.Length;
                string ext = fi.Extension;
                if (string.IsNullOrEmpty(ext)) ext = "[no extension]";
                if (!extensionCounts.ContainsKey(ext))
                    extensionCounts[ext] = 0;
                extensionCounts[ext]++;
            }
            catch (Exception ex)
            {
                Console.WriteLine($"[Skipped] {file}: {ex.Message}");
            }
            if (++fileIndex % 100 == 0)
            {
                Console.WriteLine($"Processed {fileIndex} files...");
            }
        }
        Console.WriteLine($"
Total size: {totalSize / 1024.0 / 1024.0:F2} MB");
        Console.WriteLine("File counts by extension:");
        foreach (var kvp in extensionCounts.OrderByDescending(k =andgt; k.Value))
        {
            Console.WriteLine($"  {kvp.Key}: {kvp.Value}");
        }
    }
}
Sample Output:
Processing files...
Processed 100 files...
Processed 200 files...
Total size: 153.42 MB
File counts by extension:
  .txt: 92
  .log: 65
  .json: 31
  [no extension]: 5
