C# Directory Operations

The Directory and DirectoryInfo classes let you create, browse, and manage folders.

1 - Create and Check

Directory.Exists("uploads");                  // true/false
Directory.CreateDirectory("uploads/images");  // creates all missing segments

string current = Directory.GetCurrentDirectory();
Console.WriteLine(current);

2 - List Files and Subdirectories

// All files in a directory
string[] files = Directory.GetFiles("logs");
foreach (string f in files)
    Console.WriteLine(f);

// Filter by extension
string[] textFiles = Directory.GetFiles("docs", "*.txt", SearchOption.AllDirectories);

// Subdirectories
string[] dirs = Directory.GetDirectories("src");

3 - DirectoryInfo

var dir = new DirectoryInfo("uploads");

foreach (FileInfo file in dir.GetFiles("*.png"))
{
    Console.WriteLine($"{file.Name} — {file.Length} bytes");
    // Process each PNG...
}

4 - Move and Delete

Directory.Move("old-folder", "new-folder");

// Delete (must be empty by default)
Directory.Delete("temp");

// Delete with all contents
Directory.Delete("temp", recursive: true);
