Hi Russell,
>I have a weird situation where I'm generating some text files and VFP tells me the file name is an invalid path/filename.
That happens when one of the parent direcories has the hidden or system attribute set. Some parts in VFP deal with this properly, others try to validate the file name by parsing the full path from the root down to the file. That code ignores hidden and system files making VFP assume that the directory does not exist. Hence, the error. You can see this pretty good with FILEMON from sysinternals.
