When I do a deployment or try to "unlink" a project directory from SVN, I need to remove all ".svn" folders. I know we can use Windows Search to find all folders call ".svn" or run a few lines of command in Linux. But that is not enough easy. I found a tool calls SVN-Cleaner. You just need to right click the folder you want to delete its ".svn" folders and select "Remove all .svn" in the window context menu. Then Job Done! That's easy!
