        Just another thought: it's not obvious from your original message
that you are aware that there are two different "current directories" for

There is the one used by the Front End (e.g. to save the notebook).

There is also the one used by the Kernel and which corresponds to the "." in
the $Path list.  Evaluating Directory[] will tell you what this is and you
can change it with SetDirectory[].   (In network installations particularly,
the default value can sometimes be quite useless.)

The cannot always be the same because you can work in a fresh untitled
notebook that has not been saved, not to mention the possibility that the
Front End and Kernel may be running on different computer systems via

Personally, I have a SetDirectory[] to a general purpose folder such as My
Documents in my init.m file for the kernel but many of my saved notebooks
start with the same

Sorry if you knew that already ...
