A few hints:

1. Get all files (recursively if you want) with

   Directory.GetFiles(@"c:\folder\")

2. Rename all files with

   File.Move(@"C:\folder\oldname", @"C:\folder\newname");

If your file format is like that you can simply split the filename at "-" & replace the first part with your name.

You can use the FolderBrowserDialog class to select the directory, the Directory class to rename it and String.Split or a RegEx to modify the name.

Store the selected directories and their names to a collection of your choice.

The Directory Class will do this.

You should also take a look at Path to help figure out what to replace.

http://msdn.microsoft.com/en-us/library/system.io.path_members(v=VS.71).aspx

// Move the directory.
Directory.Move(path, target);

Use others answers and for renaming i would do a RegEx replace like this.

string new_folder_name = Regex.Replace(/*old folder name*/, @"\d\d\d\d", /*user provided name*/)

In the command prompt the following

for /L %n in (1991,1,2010) do ren "(%n) - *" "name - *"

should do what you want.
