Syntax	Dir.Exists (directoryPathName : string) : boolean
Description	Dir.Exists returns true if a directory by the name of directoryPathName exists. It will return false if directoryPathName is a file.
Details	If the Dir.Exists returns false, you can examine Error.Last or Error.LastMsg for more information (i.e. whether the path failed or the directory was simply not found).
Example	The following program determines if the directory "d:/usr/west" exists, and outputs an error message if it does not. if Dir.Exists ("d:/usr/west") then put "Directory exists" else put "Directory does not exists: ", Error.LastMsg end if
Status	Exported qualified. This means that you can only call the function by calling Dir.Exists, not by calling Exists.
