Files

Work with files programmatically (read, write, copy, rename, and so on).

Background

ObjectScript provides commands for working with files and other devices.

Available Tools

In addition, InterSystems provides the following tools:

%File class

Represents disk files and provides utility methods for working with files, directories, and drives. This class includes instance methods like the following:

  • Clear()

  • Open()

  • Rewind()

  • And others

And it also contains class methods like the following:

  • ComplexDelete()

  • CopyFile()

  • ManagerDirectory()

  • NormalizeFilenameWithSpaces()

  • Rename()

  • SetReadOnly()

  • TempFilename()

  • And others

Note that this class is a fairly simple wrapper around the ObjectScript file commands. For simply reading or writing to a file, it is suggested that you use the file stream classes. These open the file using the correct mode automatically in order to read or write to the file and thus are simpler to use.

Availability: All namespaces.

file adapters

Enable a production to read and write files. See Using File Adapters in Productions.

These adapters are included automatically in many specialized business host classes.
