Here is my version of Shell / context menu extension to remove all .svn folders (used by Subversion).
This reg file adds menu item called ‘Delete SVN Folders’ under Right mouse click on folder.
Download and run this file: DeleteSVN.reg
Here is a full source of DeleteSVN.reg:
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 && echo Confirm to permanently delete all .svn folders. This operation cannot be undone! && pause && FOR /r \"%1\" %%f IN (.svn) DO RD /s /q \"%%f\" \""
Tested on Windows Vista and Windows 7.
