MATLAB: Dir or ls are not working properly

MATLAB

Hi,
I have a remote folder and there are many .mat files in it. I can see those files in windows explorer.
But in matlab command window, can cd into the folder by:
>cd rfolder
but dir or ls only show ". .." not those .mat files at all. I used to be able to ls or dir all the file names.
Why? Should I somehow add some path into matlab?
Thanks for any help.

You mentioned it is a remote folder. Often times changes made to remote folders after matlab has started wont' be recognized by matlab. The fix for this problem is to rehash path
