2.7: Chapter Summary

FileSystem is a powerful and elegant library to manipulate files. It is a fundamental part of Pharo. The Pharo community will continue to extend and build it. The class FileReference is the most important entry point to the framework.

• FileSystem offers factory class methods to build file systems on hard disk and in memory.
• FileReference is a central class in the framework which represents a file or a folder. A file reference offers methods to operate on a file and navigate within a file system.
• Sending the message asFileReference to a string character returns its corresponding file reference (e.g., '/tmp' asFileReference)
• Creating a file and writing in it is as simple as: (FileSystem disk workingDirectory / 'foo.txt') writeStreamDo: [ :stream | stream nextPutAll: 'Hello World' ].
• FileLocator is a late binding reference, useful when the file location in a hard disk depends on the running context.
• FileSystemDirectoryEntry offers a large set of low level detail for a given file.
