Re: Linking to another file.
I can't say I 100% understand what you're trying to accomplish...
However, to create a path that can be redirected to different versions of y.dat use subst
(Type help subst in a shell window)
Re: Linking to another file.
Well basically. X.exe accesses y.dat. It's behavior is based on y.dat. If I modify y.dat, x.exe behaves differently. I have two versions of y.dat. y.dat is very large. How can I easily determine which y.dat x.exe accesses without having to move a large amount of data. In other words, could I create my own y.dat, which x.exe accesses, that would in turn load the y.dat in a different folder that I want.
