 creates a directory named TeStDiReCtOrY. If you rename a directory or file to change its case, the directory or file name reflects the case of the string used when you rename it. For example, the following code renames a file named test.txt to Test.txt:
 
-```csharp
-using System;
-using System.IO;
-
-class Example
-{
-   public static void Main()
-   {
-      var fi = new FileInfo(@".\test.txt");
-      fi.MoveTo(@".\Test.txt");
-   }

 However, directory and file name comparisons are case-insensitive. If you search for a file named "test.txt", .NET file system APIs ignore case in the comparison. Test.txt, TEST.TXT, test.TXT, and any other combination of upper- and lowercase letters will match "test.txt".
