After each string is created you need to display it, or use the debugger, to see exactly what you are creating.

This will create a file in the MyDocuments folder called userdata.text. File will be wrote to the Stopwatch Data folder, as I believe you were trying to do?

var dir = Path.Combine(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Stopwatch Data")); 
/* Path.Combine combines two paths */

if (!Directory.Exists(dir)) /* Check if the directory exists */
Directory.CreateDirectory(dir); /*If it doesn't, we create it */

StringBuilder sb = new StringBuilder();

foreach (string Item in listBox2.Items)
{
    sb.AppendLine(Item); 
    /* Appends a new line with the item value from the listbox */
}

var file = Path.Combine(dir, "userdata.text"); /* Combine the directory with the file name */

File.WriteAllText(file, sb.ToString()); 
/* Write the file. If not exists, it will create it. If exists, it will overwrite it */

Hi,

1. the code shown does not compile
2. once the compile error gets fixed, it runs and creates a file (Not where you expect it!)
3. you should not use + to combine path parts, that is what Path.Combine is for (and it may be useful to know it accepts more than two arguments!)
4. you should not compute the folder name twice
5. when you forget a "directory separator" (a slash) you get an unexpected file one level up in the file hierarchy
6. you should put experimental (or even all) code in a try/catch block and display and/or log to a file any exception that occurs
7. and finally simple problems like this should be easily solved by using the debugger: single-step the code, watch the variables, and find the problems.
