Is it possible on Windows NT to have one directory sort of on top of another?
For example I have a directory like this:
C:\foo
It has a file in it called zoo.txt
I have another directory like this:
C:\bar\baz
It has the file museum.txt
in it.
I would like to be able to talk about C:\foo\museum.txt
and automatically get C:\bar\baz\museum.txt
.
Additionally, if a file named C:\bar\baz\zoo.txt
is ever created, I would like that file when referencing C:\foo\zoo.txt
Lastly, if I create a file named C:\foo\qux.txt
I would like that file to actually appear in C:\bar\baz\qux.txt
and if I ever cancel the overlay mount or whatever mechanism I'm using to make this happen, it will disappear from C:\foo\qux.txt
Are these things possible?
Basically, I have a vendor supplied directory that needs to have some source code overlaid on top of it and compiled. But I would like the actual vendor supplied directory to remain in the state it was when it was shipped from the vendor.
Right now a backup is kept of this directory, and it is restored from backup before the source code is built, then the current version of the source code is copied onto it. This is very inefficient and error prone.
