When deploying websites, all SVN folders should be deleted, but SVN doesn’t include any built in commands to do this.
The registry hack below can do this for you – it adds “Delete SVN Folders” to the context menu for folders. When you select it, it removes all folders named .svn inside the folder and it’s children (it does nothing if the project’s not under Subversion source control.
Just add the code to a reg file and then run it. The command should appear when you right click a SVN folder.
