I’ve been looking into centralising my computer game saves to make it easier to backup and restore as well as putting them up on the cloud via dropbox but there in so may places that it makes it quite difficult. I noticed the Windows 7 and Vista now support Symbolic links so I’ve been playing around with that but I was wonder the follow:

Is it possible (code example or a point in the right direction) for an application (vb.net or C++) to spoof a file or folder?

E.g. Application A (a game like Diablo III or Civilization V) attempts to read or right from file A (the game save), application B (the save repository) detects this read/write request and pipes the request through itself preforming the request on file B (the actual game save in another location). Application A is in no way altered and treats the file normally.

Note: I realise there are many simple ways of preforming the same task in essence such as monitoring the use of Application A or periodically checking file A and copying it if it has been altered since the last check etc but all these methods have draw backs and less interested in making it work than if it is possible.

    It is entirely possible to do this through a file system filter driver. For information about these, take a look here:

    Filter drivers can hook into CreateFile operations and redirect the create to a different place if you want, but they are much harder to write as compared to normal applications. They run in kernel mode and must obey the limitations of drivers.
