System i uses multiple file systems. Among some others, there are:
All of the various file systems taken together are known as the IFS (Integrated File Systems).
The /QDLS file system is similar to the old FAT file system in its naming convention which follows 8.3 rules. But it also includes various OS/2 HPFS elements such as extended attributes.
The /QOpenSys file system mostly follows rules appropriate to UNIX systems, including case-sensitive names.
The /root file system appears somewhat similar to NTFS from the external program perspective
Overall, the IFS is designed to allow IBM to release new file systems whenever it’s appropriate. Technically, you can create user-written file systems or user-defined file systems (UDFS) too.
So,We can say…AS/400 is a collection of file systems..right?

A first introduction to IFS concepts is the Overview of the integrated file system topic in the Information Center.
The navigation pane will show that topic within a number of related IFS topics, including a topic that describes all of the standard file systems.
