Re: invalid extension

The "traditional" iSeries file system doesn't use "extensions" per-se. 
When you have a program, you don't have to end it with .EXE, it knows it's 
a program because it's an object of type *PGM.  Similarly, a file doesn't 
have to end with .TXT or .DAT (or whatever else) it knows it's a file 
because it's an object of type *FILE.

When you access the traditional file system through the IFS, you use 
pathnames with "extensions", but they're not _really_ extensions.  They're 
just file types.  So you might have:

If you had a file called MYLIB/MYFILE with a member named MYMBR, the IFS 
pathname would look like this:

   /QSYS.LIB/MYLIB.LIB/MYFILE.FILE/MYMBR.MBR

You can't rename MYMBR.MBR to end with .CMP or .TXT or anything else like 
that. It's an object of type *MBR, and the only valid extension is .MBR. 
Similarly MYFILE.FILE must always end with .FILE.  You can't rename the 
extension.

On the other hand, if you use "root" or "QOpenSys" filesystems in the IFS 
for your tests, you won't have this problem, since they do use extensions 
in a Windows or Unix-like manner, instead of using the OS/400 object 
types.

Note that this error message has little or nothing to do with FTPAPI -- 
it's a message that's being sent to you from the FTP server. All FTPAPI 
does is relay it back to you so that you can read it for yourself.

If this doesn't answer your question, then please post a code snippet with 
enough info that I can reproduce the error on my system.
