The Subversion source control client maintains your local state in hidden folders named .svn inside your project, which can be a problem if you want to copy or share the project directory. This REG file 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.
Create a file containing the following and then run it.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN]
@="Delete SVN Folders"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN\command]
@="cmd.exe /c \"TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r \"%1\" %%f IN (.svn) DO RD /s /q \"%%f\" \""
