Re: Understanding and Using OS/400 file systems

Is your unix server an ftp server? Then it may be possible to send a physical file directly with FTP, if there are no packed fields in the physical file. And no binary fields, probably. You could also create a logicl file over the physical, with all the numerics redefined as zoned. Then FTP that logical file directly.

If you still do the CPYTOIMPF, I suggest not using /qdls - it is the old DLO (OfficeVision) file system that is restricted to DOS 8.3 naming. Besides, it's deadly slow.

/home is analogous to the same concept on unix boxes - home directories for users. You could make a folder there, or just make your destination a folder called /xfer, off the root (another unix concept).

The root file system is case-insensitive, like Windows. There is a case-sensitive file system, /QOpenSys, which is like unix. Then there is the traditional library/object file system, /QSYS.LIB.

You can see any of this from Windows by turning on NetServer and setting up file shares (just like NT, etc.). And you could even see them from a unix box if it has samba (or other Windows networking capability) on it. Linux certainly can do it. You turn on NetServer a couple ways, STRTCPSVR (NETSVR on the green screen, or in OpsNav, where you configure it, in Network->Servers->TCP/IP->NetServer, I think.

Hello,

I'm currently looking at the OS/400 file systems and where and when to use
them?

Basically, I need to FTP a physical file to an Unix system. So I do an
CPYTOIMPF to get a plain text file
and that seems to work.

But where should I create this text file:  in /home/userx or in /qdls/userx
or somewhere else? My stupid question
is , what is the difference?

Can I access /home/userx somehow from a windows pc?

Thanks,
