将下面的这段文字写在.reg结尾的文本文件中，然后在cmd中执行。这样你在每个文件夹右击的时候就会出现Delete Svn Folders这个选项了。很方便
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellDeleteSVN]
@="Delete SVN Folders"
[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellDeleteSVNcommand]
@="cmd.exe /c "TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r "%1" %%f IN (.svn) DO RD /s /q "%%f" ""
