I've got two sites in my local www folder, say site1.com and site2.com.
They are both stored in my SVN repo on the dev server, and I use tortoise SVN.
I've copied some files from one of the sites to another, but SVN now has these files linked together in the repo.
E.g. if I update main.css on site1 and commit it, when I update main.css on site2, it gets the changes I made in site1.
How can I unlink these files again?
