Hi José,

This error message is coming from the server. You can see the method
called is "checkStatus" which means JCIFS is just reporting the status
of the last command sent to the server. So I think the error message
actually means what it sounds like - the file is in fact not present
for some reason.

My guess would be that you have a race condition in your application.
Meaning after createFile is called the file has been deleted. If this
is the case, one solution would be to simply not call createNewFile().
If you really need to call createNewFile() for some logical reason,
you might try to create a new SmbFile object so that the state of the
file is created anew at the point of writing.

Mike
