You could probably do it via Mex or ActiveX (if you could find an appropriate ActiveX control)
Standard warning: the fact that a file has come in to existence seldom means that the file is ready to read. I am not aware of any MS Windows API call that can tell you that a file is "ready to be read"... especially if a networked file system is involved.

I am not familiar enough with Mex or Windows to answer this.
I do find that on MS Windows, MATLAB uses Windows Change Notification Handles internally, but I do not see any way for the users to access them.
I also seem to recall that there is a Java class that can be used to get change notifications; I have seen it posted 3 or 4 times, but unfortunately I do not seem to be able to track it down.
