There are five classes in the System.IO namespace that are very useful:
Directory - Contains shared methods that let you enumerate and manipulate directories
DirectoryInfo - Represents an individual directory and exposes methods to query its attributes and manipulate them
File - Contains shared methods that let you enumerate and manipulate files
FileInfo - Represent an individual file and exposes methods to query its attributes and manipulate them

This namespace also provides classes to allow synchronous and asynchronous reading from and writing to data strreams and files.
