i5/OS, OS/400 Integrated File System
Q. What is OS/400 IFS?
A.
IFS stands for Integrated File System.
It brings all of the other file systems
under a single umbrella.
The traditional LIBRARY/FILE system resides
in the IFS, as does the shared folder
system (QDLS) as well as a Unix-like
system named QOpenSys.
Generally, when people say "IFS" they
mean the Unix-like portion.
These Unix-like files are called stream
files, and do not necessarily contain
a fixed record length, or any record
length at all! They are treated as a
stream of bytes instead of a group of
records.
