Is it possible to combine two separate directories into the same place on Windows using symbolic links?

Something like this:

mklink /J c:\Merged c:\Data\Dir1
mklink /J c:\Merged c:\Data\Dir2

Which doesn't actually work because C:\Merged cannot be created twice.

Or maybe there is an alternative way of dong this other than symlinks?

That's not how symbolic links work. (So the answer to your question is "No", at least not with symbolic links.)

What you are looking for is called a Union Mount - I'm not aware of any way to accomplish this on Windows, though it may be possible and I've just never seen it...

Nope, not possible with anything built-in to Windows. – longneck Feb 19 '13 at 17:34
@longneck I don't think there's anything third-party either - it would be some pretty nasty filesystem hackery and I don't know anyone who would want to take that on in the Windows world... – voretaq7 Feb 19 '13 at 17:36
Thanks for the answer. I think it safe to assume it is not possible then. – NickC Feb 19 '13 at 19:27
