The Server.MapPath method can be used to retrieve several interesting properties about the running ASP application, for example:

' the current directorycurrDir = Server.MapPath(".")' the parent directoryparentDir = Server.MapPath("..")' the application's root directoryrootDir = Server.MapPath("/")

For example, you can store the application’s root directory in an Application variable, and use it to dynamically build physical paths to other files and directories.
