Directory is a new GeneXus data type that allows the management of system directories. It makes easier the development of applications that need to execute actions over system directories and files.

Description

Directory data type allows managing system directories. Use Directory data type for typical operations such as creating, copying, moving, renaming and deleting directories. You can also use the Directory data type to get the directory attributes such as modification date time and size.

Delete Deletes the specified directory.
Exists Determines whether the specified directory exists.
GetName Returns the name of the specified directory
GetAbsoluteName Returns the full path name of the specified directory
Rename Renames the specified directory
GetFiles Returns the files in the specified directory
GetDirectories Returns the directories in the specified directory

	endfor                                              endfor
