Hi,

have a look at Directory.GetFiles to get to the names of the files in a directory. If they're text files you can read them via File.ReadAllLines (returnsan array of strings, one per line of the file) or File.ReadAllText (returns a single string containing the entire content of the file).

To save the edited files have a look at File.WriteAllLines or File.WriteAllText.
