File Access with Visual Basic

The My.Computer.FileSystem object provides tools for working with files and folders. Its properties, methods, and events allow you to create, copy, move, investigate, and delete files and folders. My.Computer.FileSystem provides better performance than the legacy functions (FileOpen, FileClose, Input, InputString, LineInput, etc.) that are provided by Visual Basic for backward compatibility.
