Why use the integrated file system
The integrated file system offers the following benefits:
• Fast access to OS/400 data
• Efficient handling of stream data, including images, audio, and video
• A file system and directory base for supporting UNIX-based open system standards
such as POSIX and XPG
• File system support that lets you manage files through a common interface
• Consistent use of object names and associated object information across national
languages
A file system provides the support to access specific segments of storage that are organized
as logical units. These logical units on the AS/400 system are files, directories, libraries, and
objects.
Each file system has a set of logical structures and rules for interacting with information in
storage. These structures and rules may be different from one file system to another. In fact,
from the perspective of structures and rules, the OS/400 support for accessing database files
and various other object types through libraries can be thought of as a file system. Similarly,
the OS/400 support for accessing documents (which are really stream files) through the
folders structure may be thought of as a separate file system.
The integrated file system treats the library and folders support as separate file systems.
Other types of file management support that have differing capabilities are also treated as
separate file systems. The file systems are:
• NFS
Network File System. This file system provides the user with access to data and objects
that are stored on a remote NFS server. An NFS server can export a network file system
that NFS clients then mount dynamically.
• QDLS
The document library services file system. This file system provides access to documents
and folders.
• QFileSvr.400
This file system provides access to other file systems that reside on remote AS/400
systems.
• QLANSrv
OS/2 Warp Server for AS/400 file system. This file system provides access to the same
directories and files that are accessible through the OS/2 Warp Server for AS/400
