That is basically what I have.

SQL2008Dev

SQL2012Dev

SQL2014Dev

It is organized, but I have issues with my scripts. I have made an installer that runs scripts to build DBs for different regions. I have to be careful because they all share C:SQLData\. The scripts blow up if I create on one version and then test on another version without removing the original. Also just space in general becomes an issue. I only have a 250 gb hd and only have about 60 gb free. Once I put the DBs on there it is 20. We also just upgraded to VS 2013...What a space hog that is. I just need a new machine with a terabyte. 😀
